[patch] Table cell merging (colspan)

[trac-form@…]

The attached patch implements column spanning/merging in the Trac WikiFormatting. Syntax is very basic, though not 100% backward compatible.

The following table

|| Cell 1 || Cell 2 || Cell 3 ||
|| Cell 4 |||| Cell 5 and 6 ||

currently renders as

Cell 1	Cell 2	Cell 3
Cell 4	Cell 5 and 6

but with this patch renders as

Cell 1	Cell 2	Cell 3
Cell 4	Cell 5 and 6

Patch implementing table column spanning

[anonymous]

Nice improvement, but I would think cell 4 and 5 would have been merged in your example. Merging the empty cell with the previous cell rather then the next one makes more sense to me.

How about something like this?

|| Cell 1 || Cell 2 || Cell 3 ||
|| Cell 4 ||| Cell 5 and 6 |||
|||| Cell 7, 8 and 9 ||||

Cell 1	Cell 2	Cell 3
Cell 4	Cell 5 and 6
Cell 7, 8 and 9

I'm not sure I like either of these syntax proposals. As far as I can tell they only allow a "colspan" of 1 or 2. We should probably support larger colspans as well…

Another Moin wiki table columns span syntax

[sergeych <sergeych@…>]

The proposed patch adds MoinMoin wiki table column span syntax with any span size: the opening 'column' symbol

width denotes the spanning:

|||||| 1+2+3 ||
|| 1 |||| 2 + 3 ||
|||| 1+2 || 3 ||
|| 1 || 2 || 3 ||

The wiki syntax had never been overly stylish but it is known and handy.

Ok, I'll have a look at integrating this as soon as we start the 0.11 development cycle.

Changing title to include [patch] and adding review keyword

[Christian Boos]

Note that there are also two other alternatives to consider: the DokuWiki ​table syntax (see #771 and the formatter patch) and the MediaWiki way (see #1424).

[jan@…]

Another approach to having richer tables.

[jan@…]

The patch attachment:table_cell_attributes.patch​ I added makes allows for the following syntax:

|| A || B || C ||
||rowspan="2"| X || B2 || C2 ||
|| B3 || C3 ||

It's probably not the best way, but it's a quick and easy fix to allow both colspans and rowspans. Optionally, you can use it to add extra markup too.

MoinMoin compatible syntax described in #comment:description implemented in r8698.
