Yes, a table-like/grid-based layout system would be quite useful in SVG.

But there's a difference between

(eg SVG2)

<grid>
<grid-row><!-- button --></grid-row>
<grid-row><!-- label --></grid-row>
</grid>

and (similiar to XHTML)

<table summary="'Monday' in English and German.">
<table-caption>A Day of the Week.</table-caption>
<table-row>
<table-header scope="column">English</table-header>
<table-header scope="column">German</table-header>
</table-row>
<table-row>
<table-cell>Monday</table-cell>
<table-cell>Montag</cell>
</table-row>
</table>

IMHO:

If there's layout to be done, then layout markup is to be used (not
table markup). For example SVG 1.2 or 2.0.

If there's tabular data (eg name of the weekdays in five languages),
then table markup is to be used, with all the features which were
designed to be used for tabular data, eg XHTML: table with attribute
summary, caption, tr, th, td, (both with attribute scope) etc.
See
http://www.w3.org/TR/SVG11/extend.html#ForeignObjectElement
http://www.w3.org/TR/SVG11/extend.html#AnExample
etc

This should help accessibility.

I hoped we overcame the "tables work well for layout (of non-tabular
data)" strategy of abuse :)
