INTRODUCTION *table-mode-introduction*
Table Mode is simple plugin that makes building tables in vim a breeze. It is
inspired from tpope's auto aligning script for creating tables in vim -
https://gist.github.com/tpope/287147, which in turn utilizes the Tabular
Plugin.
===============================================================================
GETTING STARTED *table-mode-getting-started*
Create Table on the fly:
Using Table Mode is dead simple. You simply start typing on a new line
with the table separator - |g:table-mode-separator|, and you just type
away! The plugin does the rest automatically for you as you type. With
each additional separator you add, it aligns the table properly,
without having to do anything else.
The table mode is disabled by default and you can enter table mode
using |table-mode-toggle-map| or you can also enable it permanently
using |table-mode-always-active| if you wish though not recommended.
Table Mode allows for creation of tables within comments, it looks at
the 'commentstring' setting to identify whether the current line is
commented.
Tableize content:
Table Mode enables conversion of delimited text into tables. Again
like table creation, this is also applicable within comments.
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 |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.
Manipulation of tables:
Tableize provides 3 easy ways to quickly manipulate tables.
1. Cell Text Object : A text object for table cell
defined by |table-mode-cell-text-object|. You can use it with an
operator (d,c,y) to manipulate it easily. If you delete the cell using
this, it will delete the table separator along with it so if you type
out some new stuff, you will have to re-add it, which triggers a
re-alignment and the table would be formatted again.
2. Delete Column : Delete an entire table column using
|table-mode-delete-column-map| .
3. Delete Row : Delete an entire table row using
|table-mode-delete-row-map|
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
|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 also 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=$3/3.14'
You can evaluate the formula line using |:TableEvalFormulaLine| or the
mapping |<Leader>tfe| defined by the option |table-mode-expr-calc-map|
Formula Expressions :
Expressions are of the format '$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.
Apart from basic mathematical expressions, table mode also provides
special functions 'Sum' and 'Average'. Both these functions take a
range as input. A range can be of two forms :
'n,m': This represents cells in the current column from row
'n' through 'm'. If 'm' is negative it represents 'm' row
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 = $1 / $1,3
$1,2 = $1,1 * $1,1
$5,1 = Sum(1:-1)
$5,3 = Sum(1,2:5,2)

g:loaded_table_mode *table-mode-loaded*
Use this option to disable the plugin: >
let g:loaded_table_mode = 1
<
g:table_mode_corner *table-mode-corner*
Use this option to define the table corner character: >
let g:table_mode_corner = '+'
<
g:table_mode_separator *table-mode-separator*
Use this option to define the table column separator character: >
let g:table_mode_separator = '|'
<
This option also defines the trigger to be used to start creating a
table row in insert mode.
g:table_mode_fillchar *table-mode-fillchar*
Use this option to define the table header border fill character: >
let g:table_mode_fillchar = '-'
<
g:table_mode_map_prefix *table-mode-map-prefix*
Use this option to define the table mode mapping prefix that will be
prefixed for all other table mode mappings. >
let g:table_mode_map_prefix = '<Leader>t'
<
g:table_mode_toggle_map *table-mode-toggle-map*
Use this option to define the mapping for toggling the table mode: >
let g:table_mode_toggle_map = 'm'
<
Read |table-mode-mappings-toggle| for more info.
NOTE you will need to use the |table-mode-map-prefix| before this to
get the desired effect.
g:table_mode_always_active *table-mode-always-active*
Use this option to permanently enable the table mode: >
let g:table_mode_always_active = 0
<
This will trigger table creation once you type the
|table-mode-separator| as long as it's the first character on
the line, which can be annoying. I recommend you to instead use the
|table-mode-mappings-toggle| or |table-mode-commands-toggle| to toggle
the table mode or |table-mode-commands-enable| to enable and
|table-mode-commands-disable| to disable mode when needed.
g:table_mode_delimiter *table-mode-delimiter*
Use this option to define the delimiter which used by
|table-mode-commands-tableize| >
let g:table_mode_delimiter = ','
<
g:table_mode_tableize_map *table-mode-tableize-map*
Use this option to define the mapping to invoke |:Tableize| with
default delimiter, i.e. |:Tableize| without input. >
let g:table_mode_tableize_map = 't'
<
g:table_mode_tableize_op_map *table-mode-tableize-op-map*
Use this option to define the mapping to invoke |:Tableize| with input
parameter. This option will ask for command-line input {pattern} that
defines the delimiter. >
let g:table_mode_tableize_op_map = '<Leader>T'
<
g:table_mode_realign_map *table-mode-realign-map*
Use this option to define the mapping for realigning table columns.
This is useful in case you make edits to an existing table. >
let g:table_mode_realign_map = 'r'
<
NOTE you will need to use the |table-mode-map-prefix| before this to
get the desired effect.
g:table_mode_cell_text_object *table-mode-cell-text-object*
Use this option to define the table mode cell text object. >
let g:table_mode_cell_text_object = 'tc'
<
This text object automatically selects different text depending on the
context.
If you delete the cell using either the 'd' or the 'c'
operator, it will delete cell contents along with the table separator.
In case you do it with 'c' while you add new content for the cell, you
will have to re-add the |table-mode-separator|, which will trigger the
re-alignment of the table again and format it correctly.
If you simply want to yank the table content, this text object will
select only the table cell contents, without the padding (extra space
around the text) or the |table-mode-separator|.
g:table_mode_delete_row_map *table-mode-delete-row-map*
Use this option to define the mapping for deletion of the entire table
row. You can delete multiple rows by preceeding this with a [count]. >
let g:table_mode_delete_column_map = 'dd'
<
NOTE you will need to use the |table-mode-map-prefix| before this to
get the desired effect.
g:table_mode_delete_column_map *table-mode-delete-column-map*
Use this option to define the mapping for deletion of the entire table
column. You can delete multiple columns to the right by preceeding
this with a [count] >
let g:table_mode_delete_column_map = 'dc'
<
NOTE you will need to use the |table-mode-map-prefix| before this to
get the desired effect.
g:table_mode_add_formula_map *table-mode-add-formula-map*
Use this option to define the mapping for invoking |TableAddFormula|
command. >
let g:table_mode_add_formula_map = 'fa'
<
NOTE you will need to use the |table-mode-map-prefix| before this to
get the desired effect.
g:table_mode_eval_expr_map *table-mode-eval-expr-map*
Use this option to define the mapping for invoking
|TableEvalFormulaLine| command. >
let g:table_mode_eval_expr_map = 'fe'
<
NOTE you will need to use the |table-mode-map-prefix| before this to
get the desired effect.
===============================================================================
MAPPINGS *table-mode-mappings*
*table-mode-mappings-prefix*
<Leader>t This is a prefix defined by the option |table-mode-map-prefix|
used before all other table mode commands.
*table-mode-mappings-toggle*
<Leader>tm Toggle table mode for the current buffer. You can change this
using the |toggle-mode-options-toggle-map| option.
NOTE This is applicable only if
|table-mode-always-active| is not set.
*table-mode-mappings-trigger*
| Trigger table creation in table mode. You can change this
using the |toggle-mode-options-separator| option.
<Leader>tt Triggers |table-mode-commands-tableize| on the visually
selected content.
*table-mode-mappings-op-trigger*
<Leader>T Triggers |table-mode-commands-tableize| on the visually
selected asking for user to input the delimiter.
*table-mode-mappings-realign*
<Leader>tr Realigns table columns
*table-mode-mappings-motions*
<Leader>t[hjkl] Move to previous | below | above | right cell in the table.
*table-mode-mappings-delete-row*
<Leader>tdd Delete the entire table row you are on or multiple rows using
a [count]. You can change this using |table-mode-delete-row-map|
option.
*table-mode-mappings-delete-column*
<Leader>tdc Delete entire table column you are within. You can preceed it
with a [count] to delete multiple columns to the right. You
can change this using |table-mode-delete-column-map| option.
*table-mode-mappings-add-formula*
<Leader>tfa Add a fomula for the current table cell. This invokes
|TableAddFormula| command.
*table-mode-mappings-evaluate-formula-line*
<Leader>tfe Evaluate the formula line which is a commented line right
after the table beginning with 'tmf:'. If one exists this
would evaluate the formula line and update the table
accordingly. This invokes the |TableEvalFormulaLine| command.
+- Expands to a header border, the line immidiately above this
will be considered as the table header. You can change this by
changing |table-mode-corner| and |table-mode-fillchar|
options. This is an iabbrev so is triggered when you press
space or <CR> after typing the mapping.
===============================================================================
COMMANDS *table-mode-commands*
*:TableModeToggle*
*table-mode-:TableModeToggle*
:TableModeToggle
Toggles the table mode. Same effect as |toggle-mode-mappings-toggle|.
NOTE this is applicable only if |table-mode-always-active| is
not set.
*:TableModeEnable*
*table-mode-:TableModeEnable*
:TableModeEnable
Enables Table Mode.
NOTE this is applicable only if |table-mode-always-active| is
not set.
*:TableModeDisable*
*table-mode-:TableModeDisable*
:TableModeDisable
Disables Table Mode.
NOTE this is applicable only if |table-mode-always-active| is
not set.
*:Tableize*
*table-mode-:Tableize*
:Tableize
This converts the current line into a table if it consists of
|table-mode-delimiter|. This accepts a range, without which it
applies on the current line.
This accepts a {pattern} similar to Tabular which defines the
delimiter. eg.) >
:Tableize/;
<
The above command will Tableize using ';' as the delimiter.
NOTE this is optional, by default without the expression it will
tableize the content using |table-mode-delimiter| as the delimiter.
*:TableAddFormula*
*table-mode-:TableAddFormula*
:TableAddFormula
This command is for defining a formula for the current table cell. It
takes input on the cmd-line with a 'f=' prompt and appends it to the
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.
*:TableEvalFormulaLine*
*table-mode-:TableEvalFormulaLine*
:TableEvalFormulaLine
This command when invoked from anywhere within the table or directly
on the formula line evaluates it and updates the table accordingly.
