-# VIM Table Mode [![Build Status](https://travis-ci.org/dhruvasagar/soulmate_rails.png?branch=master)](https://travis-ci.org/dhruvasagar/soulmate_rails)
+# VIM Table Mode v4.8.1 ![Build](https://github.com/dhruvasagar/vim-table-mode/actions/workflows/ci.yml/badge.svg)
 
 An awesome automatic table creator & formatter allowing one to create neat
 tables as you type.
 
+## Getting Started
+
+### Installation
+
+#### <a href="https://www.danielfranklin.id.au/vim-8-package-management/">Vim 8+ native package manager</a>
+
+clone into `.vim/pack/plugins/start` (the `plugins` folder can have any name)
+
+Add `packloadall` in your `~/.vimrc`.
+
+#### <a href="https://github.com/Shougo/neobundle.vim">NeoBundle</a>
+
+Add `NeoBundle 'dhruvasagar/vim-table-mode'` to your `~/.vimrc`.
+
+#### <a href="https://github.com/tpope/vim-pathogen">pathogen.vim</a>
+
+Add a git submodule for your plugin:
+
+```sh
+$ cd ~/.vim
+$ git submodule add git@github.com:dhruvasagar/vim-table-mode.git bundle/table-mode
+```
+
+Copy all files under `autoload/`, `plugin/`, and `doc/` to respective
+`~/.vim/autoload/`, `~/.vim/plugin` and `~/.vim/doc` under UNIX, or
+`vimfiles/autoload/`, `vimfiles/plugin/` and `vimfiles/doc` under WINDOWS and
+restart Vim.
+
+#### <a href="https://github.com/junegunn/vim-plug">vim-plug</a>
+
+Add `Plug 'dhruvasagar/vim-table-mode'` to your `~/.vimrc`.
+
+### Creating table on-the-fly
+
+To start using the plugin in the on-the-fly mode use `:TableModeToggle` mapped to <kbd>\<Leader\>tm</kbd> by default (which means <kbd>\\</kbd> <kbd>t</kbd> <kbd>m</kbd> if you didn't override the <Leader> by `:let mapleader = ','` to have <kbd>,</kbd> <kbd>t</kbd> <kbd>m</kbd>).
+
+Tip:
+You can use the following to quickly enable / disable table mode in insert mode by using `||` or `__`:
+
+> ```vim
+> function! s:isAtStartOfLine(mapping)
+>   let text_before_cursor = getline('.')[0 : col('.')-1]
+>   let mapping_pattern = '\V' . escape(a:mapping, '\')
+>   let comment_pattern = '\V' . escape(substitute(&l:commentstring, '%s.*$', '', ''), '\')
+>   return (text_before_cursor =~? '^' . ('\v(' . comment_pattern . '\v)?') . '\s*\v' . mapping_pattern . '\v$')
+> endfunction
+>
+> inoreabbrev <expr> <bar><bar>
+>           \ <SID>isAtStartOfLine('\|\|') ?
+>           \ '<c-o>:TableModeEnable<cr><bar><space><bar><left><left>' : '<bar><bar>'
+> inoreabbrev <expr> __
+>           \ <SID>isAtStartOfLine('__') ?
+>           \ '<c-o>:silent! TableModeDisable<cr>' : '__'
+> ```
+
+Enter the first line, delimiting columns by the `|` symbol. The plugin reacts by inserting spaces between the text and the separator if you omit them:
+
+    | name | address | phone |
+
+In the second line (without leaving Insert mode), enter `|` twice. The plugin will write a properly formatted horizontal line:
+
+    | name | address | phone |
+    |------+---------+-------|
+
+When you enter the subsequent lines, the plugin will automatically adjust the formatting to match the text you’re entering every time you press `|`:
+
+    | name       | address | phone |
+    |------------+---------+-------|
+    | John Adams |
+
+Go on until the table is ready:
+
+    | name            | address                  | phone      |
+    |-----------------+--------------------------+------------|
+    | John Adams      | 1600 Pennsylvania Avenue | 0123456789 |
+    |-----------------+--------------------------+------------|
+    | Sherlock Holmes | 221B Baker Street        | 0987654321 |
+    |-----------------+--------------------------+------------|
+
+Then you can return to the first line and above it enter `||`:
+
+    |-----------------+--------------------------+------------|
+    | name            | address                  | phone      |
+    |-----------------+--------------------------+------------|
+    | John Adams      | 1600 Pennsylvania Avenue | 0123456789 |
+    |-----------------+--------------------------+------------|
+    | Sherlock Holmes | 221B Baker Street        | 0987654321 |
+    |-----------------+--------------------------+------------|
+
+Corner separators are adjustable:
+
+For Markdown-compatible tables use
+
+    let g:table_mode_corner='|'
+
+
+    |-----------------|--------------------------|------------|
+    | name            | address                  | phone      |
+    |-----------------|--------------------------|------------|
+    | John Adams      | 1600 Pennsylvania Avenue | 0123456789 |
+    |-----------------|--------------------------|------------|
+    | Sherlock Holmes | 221B Baker Street        | 0987654321 |
+    |-----------------|--------------------------|------------|
+
+To get ReST-compatible tables use
+
+    let g:table_mode_corner_corner='+'
+    let g:table_mode_header_fillchar='='
+
+
+    +-----------------+--------------------------+------------+
+    | name            | address                  | phone      |
+    +=================+==========================+============+
+    | John Adams      | 1600 Pennsylvania Avenue | 0123456789 |
+    +-----------------+--------------------------+------------+
+    | Sherlock Holmes | 221B Baker Street        | 0987654321 |
+    +-----------------+--------------------------+------------+
+
+Markdown and ReST filetypes have automatically configured corners.
+
+> If you wish to override their configurations, it should be done in an after
+> plugin, for example :
+>
+> In a `$VIM/after/ftplugin/markdown/custom.vim` you can add the following :
+>
+> ```viml
+> let b:table_mode_corner='+'
+> ```
+
+You can also define in a table header border how its content should be
+aligned, whether center, right or left by using a `:` character defined by
+`g:table_mode_align_char` option.
+
+If you manipulate the table when table mode is disabled or copy paste a table
+from clipboard from outside and it ends up being misaligned, you can realign
+it using `:TableModeRealign` or using the default mapping
+<kbd>\<Leader\>tr</kbd> (defined by the option `g:table_mode_relign_map`).
+
+### Formatting existing content into a table
+
+Table Mode wouldn't justify its name if it didn't allow formatting
+existing content into a table. And it does as promised. Like table creation typing on the fly,
+formatting existing content into a table is equally
+simple. You can visually select multiple lines and call `:Tableize` on it.
+Alternatively, the mapping <kbd>\<Leader\>tt</kbd> can be used (defined by the
+option `g:table_mode_tableize_map`). This converts CSV (Comma-separated
+Values) data into a table.
+
+If however you wish to use a different delimiter, you can use the command
+`:Tableize/{pattern}` in a similar fashion as you tabulate (e.g.
+`:Tableize/;` uses ';' as the delimiter) or use the mapping <kbd>\<Leader\>T</kbd>
+(defined by the option `g:table_mode_tableize_op_map`) which takes input in the
+cmd-line and uses the `{pattern}` input as the delimiter.
+
+`:Tableize` also accepts a range. Call it by giving
+lines manually like `:line1,line2Tableize`. However this may not be intuitive.
+You can use the mapping <kbd>\<Leader\>T</kbd> with a `[count]` to apply it to the
+next `[count]` lines in standard vim style.
+
+### Moving around
+
+Now you can move between cells using table mode motions <kbd>[|</kbd>,
+<kbd>]|</kbd>, <kbd>{|</kbd> & <kbd>}|</kbd> to move left | right | up |
+down cells respectively. The left | right motions wrap around the table
+and move to the next | previous row after the last | first cell in the
+current row if one exists.
+
+### Manipulating Table
+
+- **Cell Text Object** :
+
+  Tableize provides a text object for manipulating table cells. Following
+  the vim philosophy the you have <kbd>i|</kbd> & <kbd>a|</kbd> for the
+  inner and around (including the immediate right table separator) the
+  table cell.
+
+- **Delete Row** :
+
+  You can use the <kbd>\<Leader\>tdd</kbd> mapping (defined by the option
+  `g:table_mode_delete_row_map`) to delete the current table row (provided
+  you are within a table row). This can be preceeded with a `[count]` to
+  delete multiple rows as per Vim command grammar.
+
+- **Delete Column** :
+
+  You can use the <kbd>\<Leader\>tdc</kbd> mapping (defined by the option
+  `g:table_mode_delete_column_map`) to delete the entire current column
+  (provided you are within a table row), this can also be preceeded with a
+  `[count]` to delete multiple columns.
+
+- **Insert Column** :
+
+  You can use the <kbd>\<Leader\>tic</kbd> mapping (defined by the option
+  `g:table_mode_insert_column_after_map`) to insert a column after the
+  cursor (provided you are within a table row). Of course you can use the
+  <kbd>\<Leader\>tiC</kbd> mapping defined by
+  `g:table_mode_insert_column_before_map` to insert a column before the
+  cursor. Both can also be preceeded with a [count] to insert multiple
+  columns.
+
+### Highlight cells based on content
+
+You can highlight cells based on content by setting `let g:table_mode_color_cells` : - cells starting with `yes` will use the `yesCell` highlight group. - cells starting with `no` will use the `noCell` highlight group. - cells starting with `?` will use the `maybeCell` hightlight group.
+
+You can overwrite any highlight group. For exemple use `hi yesCell ctermfg=2` to remove the background color.
+
+## Advanced Usage: Spreadsheet Capabilities
+
+### Table Formulas
+
+Table Mode now has support for formulas like a spreadsheet. There are 2 ways
+of defining formulas :
+
+- You can add formulas using `:TableAddFormula` or the mapping <kbd>\<Leader\>tfa</kbd>
+  (defined by the option `g:table_mode_add_formula_map`) from within a table
+  cell, which will ask for input on the cmd-line with a `f=` prompt. The
+  input formula will be appended to the formula line if one exists or a new
+  one will be created with the input formula taking the current cell as the
+  target cell. The formula line is evaluated immidiately to reflect the
+  results.
+
+- You can directly add / manipulate formula expressions in the formula line.
+  The formula line is a commented line right after the table, or optionally
+  separated from the table by a single empty line. It begins with 'tmf:'
+  (table mode formula). eg) `# tmf: $3=$2*$1`. You can add multiple formulas on
+  the line separated with a ';' eg) `# tmf: $3=$2*$1;$4=$3/3.14`
+
+You can evaluate the formula line using `:TableEvalFormulaLine` or the
+mapping <kbd>\<Leader\>tfe</kbd> (defined by the option `g:table_mode_eval_expr_map`)
+from anywhere inside the table or while on the formula line.
+
+NOTE: You can now use the mapping <kbd>\<Leader\>t?</kbd>
+
+### Formula Expressions
+
+Expressions are of the format `$target = formula`.
+
+- The `target` can be of 2 forms :
+
+  - `$n`: This matches the table column number `n`. So the `formula` would
+    be evaluated for each cell in that column and the result would be placed
+    in it. You can use negative indice to represent column relative to the
+    last, -1 being the last.
+
+  - `$n,m`: This matches the table cell n,m (row, column). So in this case
+    the formula would be evaluated and the result will be placed in this
+    cell. You can also use negative values to refer to cells relative to
+    the size, -1 being the last (row or column).
+
+- The `formula` can be a simple mathematical expression involving cells
+  which are also defined by the same format as that of the target cell. You
+  can use all native vim functions within the formula. Apart from that table
+  mode also provides 2 special functions `Sum` and `Average`. Both these
+  functions take a range as input. A range can be of two forms:
+
+  - `r1:r2`: This represents cells in the current column from row `r1`
+    through `r2`. If `r2` is negative it represents `r2` rows above the
+    current row (of the target cell).
+
+  - `r1,c1:r2,c2`: This represents cells in the table from cell r1,c1
+    through cell r2,c2 (row, column).
+
+- Examples :
+  - `$2 = $1 * $1`
+  - `$2 = pow($1, 5)` NOTE: Remember to put space between the $1, and 5
+    here otherwise it will be treated like a table cell.
+  - `$2 = $1 / $1,3`
+  - `$1,2 = $1,1 * $1,1`
+  - `$5,1 = Sum(1:-1)`
+  - `$5,1 = float2nr(Sum(1:-1))`
+  - `$5,3 = Sum(1,2:5,2)`
+  - `$5,3 = Sum(1,2:5,2)/$5,1`
+  - `$5,3 = Average(1,2:5,2)/$5,1`

 ## Change Log

 See <a
 href="https://github.com/dhruvasagar/vim-table-mode/blob/master/CHANGELOG.md">
 CHANGELOG.md </a>
 
-## Getting Started
-### Installation
-
-There are several ways to do this
-
-1. I recommend installing <a
-   href="https://github.com/Shougo/neobundle.vim">NeoBundle</a> and then just
-   add `NeoBundle 'dhruvasagar/vim-table-mode'` to your ~/.vimrc
-
-2. If you are using <a
-   href="https://github.com/tpope/vim-pathogen">pathogen.vim</a>, then
-   add a git submodule for your plugin:
-
-   ```sh
-$ cd ~/.vim
-$ git submodule add git@github.com:dhruvasagar/vim-table-mode.git bundle/table-mode
-   ```
-3. Copy autoload/todomode.vim, plugin/todo-mode.vim, doc/todo-mode.txt to
-   respective ~/.vim/autoload/, ~/.vim/plugin and ~/.vim/doc under UNIX or 
-   vimfiles/autoload/, vimfiles/plugin/ and vimfiles/doc under WINDOWS and
-   restart VIM
-
-### Usage
-
-- **On the fly table creation** :
-
-   By default the table column separator is `|` defined by the
-   `g:table_mode_separator` option. As soon as you type it on a new line (ignores
-   indentation) the script gets to work on creating a table around it. As you
-   type and define more columns, the table is completed, formatted and aligned
-   automatically on the fly.
-
-   Since this could lead to unwanted behavior I have disabled table mode by
-   default. You have to use `:TableModeToggle` command or the table mode
-   toggle mapping, which is `<Leader>tm` defined by `g:table_mode_toggle_map`
-   option to toggle the table mode or you can directly use `:TableModeEnable`
-   and `:TableModeDisable` to enable or disable the table mode. This is on a
-   per buffer basis and so it does not cause any unusual behavior unless it is
-   enabled explicitly. Please read `:h table-mode` for further information.
-
-- **Format existing content into a table** :
-
-   Table Mode wouldn't justify it's name if it didn't allow formatting
-   existing content into a table. And it does as promised. Like table creation
-   on the fly as you type, formatting existing content into a table is equally
-   simple. You can visually select multiple lines and call `:Tableize` on it,
-   or alternatively use the mapping `<Leader>tt` defined by the
-   `g:table_mode_tableize_map` option which would convert CSV (Comma Separated
-   Value) data into a table and use `,` defined by `g:table_mode_delimiter`
-   option as the delimiter.
-
-   If however you wish to use a different delimiter, you can use the command
-   `:Tableize/{pattern}` in a similar fashion as you use tabular (eg.
-   `:Tableize/;` uses ';' as the delimiter) or use the mapping `<Leader>T`
-   defined by `g:table_mode_tableize_op_map` option which takes input in the
-   cmd-line and uses the `{pattern}` input as the delimiter.
-
-   `:Tableize` also accepts a range and so you can also call it by giving
-   lines manually like `:line1,line2Tableize`, but this is not very intuitive.
-   You can use the mapping `<Leader>T` with a `[count]` to apply it to the
-   next `[count]` lines in standard vim style.
-
-- **Move between cells** :
-
-   Now you can move between cells using table mode motions `<Leader>t[hjkl]`
-   to move left | down | up | right cells respectively. You can use
-   `g:table_mode_map_prefix` option to define the prefix mapping to be used
-   before 'hjkl'. The left | right motions wrap around the table and move to
-   the next | previous row after the last | first cell in the current row if
-   one exists. 
-
-- **Manipulating Table** :
-
-  - **Cell Text Object** :
-
-      Tableize provides a text object for manipulating table cells. By default
-      it's `tc`, but that can be changed if you wish to by setting the
-      `g:table_mode_cell_text_object` option.
-
-      This is intelligent in the sense that if you use it to delete the
-      contents it will delete everything till the `g:table_mode_separator` so
-      that the cell is removed and you can enter new stuff if you wish to (had
-      you used 'c' operator), having to input the `g:table_mode_separator`
-      again to form the cell & realign it (since it can't be done from the
-      text object itself). However if you were to 'y' or yank the text, it
-      would copy the right text, i.e. the contents of the cell and nothing
-      else.
-
-  - **Delete Row** :
-
-      You can use the `<Leader>tdd` mapping defined by the option
-      `g:table_mode_delete_row_map` to delete the current table row (provided
-      you are within a table row), this can be preceeded with a [count] to
-      delete multiple rows just like you would with 'dd'.
-
-  - **Delete Column** :
-
-      You can use the `<Leader>tdc` mapping defined by the option
-      `g:table_mode_delete_column_map` to delete the entire current column
-      (provided you are within a table row), this can also be preceeded with a
-      [count] to delete multiple columns.
-
-- **Table Formulas** :
-
-  Table Mode now has support for formulas like a spreadsheet. There are 2 ways
-  of defining formulas :
-
-  - You can add formulas using `:TableAddFormula` or the mapping `<Leader>tfa`
-    defined by the option `g:table_mode_add_formula_map` from within a table
-    cell, which will ask for input on the cmd-line with a `f=` prompt. The
-    input formula will be appended to the formula line if one exists or a new
-    one will be created with the input formula taking the current cell as the
-    target cell. The formula line is evaluated immidiately to reflect the
-    results.
-
-  - You can directly add / manipulate formula expressions in the formula line.
-    The formula line is a commented line right after the table, beginning with
-    'tmf:' (table mode formula). eg) `# tmf: $3=$2*$1`.  You can add multiple
-    formulas on the line separated with a ';' eg) `# tmf: $3=$2*$1;$4=$3/3.14`
-
-  You can evaluate the formula line using `:TableEvalFormulaLine` or the
-  mapping `<Leader>tfe` defined by the option `g:table_mode_eval_expr_map`
-  from anywhere inside the table or while on the formula line.
-
-- **Formula Expressions** :
-
-  Expressions are of the format `$target = formula`.
-
-  - The `target` can be of 2 forms :
-
-      - `$n`: This matches the table column number `n`. So the `formula` would
-        be evaluated for each cell in that column and the result would be placed
-        in it.
-
-      - `$n,m`: This matches the table cell n,m (row, column). So in this case
-        the formula would be evaluated and the result will be placed in this
-        cell.
-
-  - The `formula` can be a simple mathematical expression involving cells
-    which are also defined by the same format as that of the target cell.  You
-    can use all native vim functions within the formula. Apart from that table
-    mode also provides 2 special functions `Sum` and `Average`. Both these
-    functions take a range as input. A range can be of two forms :
-
-      - `r1,r2`: This represents cells in the current column from row `r1`
-        through `r2`. If `r2` is negative it represents `r2` rows above the
-        current row (of the target cell).
-
-      - `r1,c1:r2,c2`: This represents cells in the table from cell r1,c1
-        through cell r2,c2 (row, column).
-
-  - Examples :
-      - `$2 = $1 * $1`
-      - `$2 = pow($1, 5)` NOTE: Remember to put space between the $1, and 5
-        here otherwise it will be treated like a table cell.
-      - `$2 = $1 / $1,3`
-      - `$1,2 = $1,1 * $1,1`
-      - `$5,1 = Sum(1:-1)`
-      - `$5,1 = float2nr(Sum(1:-1))`
-      - `$5,3 = Sum(1,2:5,2)`
-      - `$5,3 = Sum(1,2:5,2)/$5,1`
-      - `$5,3 = Average(1,2:5,2)/$5,1`

 	formula line if it exists or adds a new formula line with the
 	expression using the current cell as the target and the input formula.
