Table formatting breaks

[kaddkaka]

Trying to format

==== =====
Head Foot
==== =====
1    1234
12   12 34
123  123 4
1234 123
==== =====

results in

+----+-----+
| Head | Foot |
+====+=====+
| 1  | 1234 |
+----+-----+
| 12 | 12  |
|    | 34  |
+----+-----+
| 123 | 123 |
|    | 4   |
+----+-----+
| 1234 | 123 |
+----+-----+

which is a broken table.

The problem seems to happen when the cell content is a single word and fills the full width of the cell or full_width-1.

Adding to this issue, formatting will also break if:

• If a span is present in the table

And formatting right now has a chance to break if:

• If the table contents contain vertical bars that use the offset

I'm looking at trying to get around this right now. It basically revolves around us parsing the whole table block as opposed to the header and rows separately, reconstructing the table geometry from the morecols and morerows attributes of occasional <entry...> objects in the rows. No idea why docutils chooses to be lossy with this info depending on the table construction...

Should be easy enough to tack on an extra whitespace row for rows containing a vertical bar in the paragraph contents in all of that other mess.

Table from hell example:

+-----------+-----------+----------+
| 1         | 2         | 3        |
+===========+===========+==========+
| 4         | 5         | 6        |
+           +-----------+          +
|           | 7         |          |
+           +-----------+          +
|           | 8         |          |
+           +-----+-----+          +
|           | 9   | 10  |          |
+-----------+-----+-----+----------+
| 11        | 12        | 13       |
+-----------+-----------+----------+
