Markdown reader - support new table features #6317
Description
Add support for (at least some of) the new table features introduced in pandoc-types/pull/66.
It would be good if at least one of pandoc markdown's table syntax would support that: grid tables seem like the obvious candidate. Something like:
+---------------+---------------+--------------------+
| Fruit | Price | Advantages |
+===============+===============+====================+
| rowspan | - built-in wrapper |
| | - bright color |
+---------------+---------------+--------------------+
| subheader | Price | Advantages |
+===============+===============+====================+
| Oranges | colspan | - cures scurvy |
| | | - tasty |
+---------------+ +--------------------+
|| Row header | | - cures scurvy |
|| | | - tasty |
+---------------+---------------+--------------------+
| Table foot | Price | Advantages |
+===============+===============+====================+
This would roughly tick off the following of the new table features:
- rowspan, colspan (note that pandoc markdown's grid tables already support this now)
- table head and foot (note that pandoc markdown's grid tables already support this now)
- multiple header lines
- row headers
- table attributes
- captions that allow block-level content and include an optional short caption
It does have the disadvantage that if the last rows look like header rows, they are simply treated as the table foot.
