mdx_spanner

This package enables rowspan and colspan in markdown tables when using MkDocs.

Syntax

Basics (spanning indicators)

You can activate colspan by putting only ~~ in a cell. This will merge the cell with the cell in the previous column.

You can activate rowspan by putting __ in a cell. This will merge the cell with the cell in the previous row. If the cell in previous row is empty it will continue to merge until it finds a non-empty cell.

Sample:

| Header 1 | Header 2 | Header 3 |
| ---------| -------- | -------- |
| Value 1  |    ~~    | Value 2  |
|          |    ~~    | Value 3  |
|_        _|    ~~    | Value 5  |
| Value 6  | Value 7  | Value 8  |

This should result in the following table:

+----------+----------+----------+
| Header 1 | Header 2 | Header 3 |
+----------+----------+----------+
| Value 1             | Value 2  |
|                     +----------+
|                     | Value 3  |
|                     +----------+
|                     | Value 5  |
+----------+----------+----------+
| Value 6  | Value 7  | Value 8  |
+----------+----------+----------+

Advanced (alignment markers)

You can change the alignment of a single spanned cell by adding markers to the spanning indicators.

To change the horizontal alignment (when multiple columns are merged) put colons before and/or after the ~~ to indicate the alignment:

Sample	Result
:~~	Left aligned
:~~:	Centered
~~:	Right aligned

To change the vertical alignment (when multiple rows are merged) put one of the following chars (`^`,`=`,`_`) between the `__` to indicate the alignment:

Sample	Result
_^_	Top aligned
_=_	Centered
___	Bottom aligned

Sample:

| Header 1   | Header 2 | Header 3 |
| ---------- | -------- | -------- |
| Value 1    |   :~~:   | Value 2  |
|            |    ~~    | Value 3  |
|_     =    _|    ~~    | Value 5  |
| Value 6    | Value 7  | Value 8  |

This should result in the following table:

+----------+----------+----------+
| Header 1 | Header 2 | Header 3 |
+----------+----------+----------+
|                     | Value 2  |
|                     +----------+
|       Value 1       | Value 3  |
|                     +----------+
|                     | Value 5  |
+----------+----------+----------+
| Value 6  | Value 7  | Value 8  |
+----------+----------+----------+
