INTRODUCTION			*Vital.Text.Table-introduction*

*Vital.Text.Table* is a character table formatter. It will make a character
table such as below:

	+---------+---------+---------+
	| header1 | header2 | header3 | <- (A) Header Row
	+---------+---------+---------+
	| r1c1    | r1c2    | r1c3    | <- (B) Body Row
	| r2c1    | r2c2    | r2c3    |
	| r3c1    | r3c2    | r3c3    |
	+---------+---------+---------+
	| footer1 | footer2 | footer3 | <- (C) Footer Row
	+---------+---------+---------+ <- (D) Horizontal Border
	^
	|
       (E) Vertical Border

	(A) Header Row
		A table header. It is configured by
		|Vital.Text.Table-Table.header()|.
	(B) Body Row
		A table body. It is configured by
		|Vital.Text.Table-Table.rows()| or
		|Vital.Text.Table-Table.add_row()|.
	(C) Footer Row
		A table footer. It is configured by
		|Vital.Text.Table-Table.footer()|.
	(D) Horizontal Border
		A horizontal border. It is configured by
		|Vital.Text.Table-Table.hborder()|.
	(E) Vertical Border
		A vertical border. It is configured by
		|Vital.Text.Table-Table.vborder()|.

|Vital.Text.Table| is easy to use. You can make a character table such above
by:
>
    let s:T = vital#of('vital').import('Text.Table')
    let s:table = s:T.new({
    \   'columns': [{}, {}, {}],
    \   'header':  ['header1', 'header2', 'header3'],
    \   'footer':  ['footer1', 'footer2', 'footer3'],
    \})

    call s:table.rows([
    \   ['r1c1', 'r1c2', 'r1c3'],
    \   ['r2c1', 'r2c2', 'r2c3'],
    \   ['r3c1', 'r3c2', 'r3c3'],
    \])

    echo s:table.stringify()
<
And you can customize the style of table by
|Vital.Text.Table-Table.border_style()|.

FUNCTIONS			*Vital.Text.Table-functions*

new([{config}])			*Vital.Text.Table.new()*
	Creates a new Table object(|Vital.Text.Table-Table|).
	You can configure a new Table object via {config}(|Dictionary|).
	{config} takes some attributes below:

	hborder (Default: 1)
		Same to |Vital.Text.Table-Table.hborder()|.
	vborder (Default: 1)
		Same to |Vital.Text.Table-Table.vborder()|.
	columns (Default: [])
		Same to |Vital.Text.Table-Table.columns()|.
	header (Default: [])
		Same to |Vital.Text.Table-Table.header()|.
	rows (Default: [])
		Same to |Vital.Text.Table-Table.rows()|.
	footer (Default: [])
		Same to |Vital.Text.Table-Table.footer()|.

OBJECTS				*Vital.Text.Table-objects*

------------------------------------------------------------------------------
Table Object			*Vital.Text.Table-Table*

				*Vital.Text.Table-Table.hborder()*
Table.hborder()
	Returns 1 If horizontal border will be drawn. Otherwise, 0.
Table.hborder({hborder})
	Controls to make a table with/without horizontal border.
	e.g. >
	table.hborder(1)
<

				*Vital.Text.Table-Table.border_style()*

	Returns a border style object(|Vital.Text.Table-BorderStyle|).
Table.border_style({style})
	Sets a border style object(). See |Vital.Text.Table-BorderStyle|
	section for more details.
	e.g. >
	table.border_style({
	\ 'joint': {
	\   'row': '+',
	\ },

	\   'right': '>',
	\ },
	\})
<

				*Vital.Text.Table-Table.vborder()*
Table.vborder()
	Returns 1 If vertical border will be drawn. Otherwise, 0.

	table.vborder(1)
<

				*Vital.Text.Table-Table.columns()*
Table.columns()
	Returns column configuration objects.
Table.columns({columns})
	Sets column configuration objects(|Dictionary|). If its object already
	has one or more rows, it will throws an exception. See
	|Vital.Text.Table-ColumnConfig| section for more details.
	e.g. >
	table.columns([
	\ {'halign': 'left',   'valign': 'top',    'width': 30},
	\ {'halign': 'right',  'valign': 'center',            },
