Hi,

To solve the colspan issue when looping on column, I plan to implement
the attrs[1] directive from Genshi.

I'm thinking about this syntax:


attrs table:table-cell="{'table:number-columns-spanned': len(loop)}"

which will means:

- find the first parent tag named: 'table:table-cell'
- set as attribute: py:attrs="{…}"

In the same idea, we we could implement: content, replace and strip.

Questions:

- should the first part be a xpath expression like:

attrs ../../table:table-cell="…"

or the generic version:

attrs .::ancestor-or-self/table:table-cell="…¨

the xpath usage will be more expensif than a simple parent
searching.

- should we instead use a dedicated directive to update span of
table-cell like:

span=len(loop)

I will be very glade to get feedback on this new feature.
It it important to get the right API to prevent non-backward compatible
change in the future.
