When I add a row, and there is a column defined as "text", "text area", or "date" next to any other column, if you don't fill in that column, than that column gets eaten by the column before as a mult-span column, which is incorrect.
To Duplicate Error:
Add a row, save. Notice that some columns turn into mutli-span.
I should get this:
| Nr | Text | Step | Radio | Text Area | Date |
| 4 | | one | :-) | | |
| 5 | test | one | :-) | test | |
| 6 | | one | :-) | | 29 November 2007 |
| 7 | | one | :-) | | |
| 8 | | one | :-) | | |
Instead I get this:
| Nr | Text | Step | Radio | Text Area | Date |
| 4 | | one | :-) | | |
| 5 | test | one | :-) | test | |
| 6 | | one | :-) | | 29 November 2007 |
| 7 | | one | :-) | | |
| 8 || one | :-) |||
There's a subtlety here that might trap the unwary.
An empty cell in a TWiki table is interpreted as an extension of a prior multicol cell. The plugin is consistent with this; if you don't provide a value for a cell, then it collapses it into a prior column. TWiki tables support cells that have no data as well, namely cells that contain just whitespace. Again, the plugin is consistent; it treats a cell that contains just whitespace as a value placeholder. The EditTablePlugin is inconsistent, because it always saves cells with whitespace, even when the cell had no whitespace when the edit started. Note that when you edit, all cells appear in the edit even when multicol cells are in use.
The tradeofff is between supporting multicol cells, and 100% consistency with EditTablePlugin. I think on balance that the EditRowPlugin does it right and EditTablePlugin is wrong. Both plugins can open a table containing colspans, but only EditRowPlugin will save it correctly. No action.
