+Status:       patch (code needs work)

No Bèr; "summary" is an attribute of "table" and is already supported
(although nowhere used) by the "$attributes" argument. "caption" is NO
attribute of "table" but an element by itself, eg it can contain HTML
code (which attributes can't contain).


So: +1 for this, but the core module theme('table') uses should be
checked to see if we can add it somewhere. So: code needs work: go
through the uses in core and add a caption where it would be usefull.

Well, if I made this patch properly :-), this patch adds a fourth
parameter to the theme_table() function, $caption.  If set, it adds a
<caption>$caption</caption> line to the table.  If it is not set, this
patch has no effect.  All styling is left up to CSS to figure out.  


It seems to me that $caption would make more sense as the 3rd
parameter, before $attributes, but that would break backward
compatibility so I just tacked it on at the end.  I'll leave the final
order of parameters up to someone else to figure out.

Hi,


I won't comment on the implementation, because I don't know the impact
of this, but from a usability pespective it is a HUGE +1 for me, as
some screen readers use either the  or  tag to describe table contents
to blind users. An example of a browser/screen reader integration that
uses the   tag is IBM's Homepage Reader.

Well, summary is an attribute of <table>, not an element in itself.  You
can already set that with the $attributes parameter.  I don't know if
the Powers That Be would want another parameter just for that
attribute, although that might increase its usage.  I just needed the
caption because I have two tables on one admin page, and not having
some way to tell them apart was not good.

+1 from me too. This is a huge accessability improvement, yet a very
small patch. 


We should follow this patch up, with a list of theme('table') calls
that should use this caption.

Yes, indeed, you are correct. Pardon my oversight that it is already a
attribute. I evaluated homepage reader about 2 months ago, and merely
recalled summary. Sorry!

I must follow Kobus. Excuse my ignorance in this too. This should indeed
be set with attributes, which already is perfectly possible. Unless
someone comes with new arguments, I suggest we close this issue as
"won't fix".
