Description From 2010-10-28 19:08:40 PST
In the table the entry 22 should be below 3 and the entries 33 and 333 should be below 3
however they appear below 1 and 2 respectively, apparently the layout has not taken account of the rowspan attribute on the entries in the first row.

perhaps related to this, the brackets in the rowspanned entries are not stretched to the height of all three rows, as they should be.

the attached file renders in firefox with the cells aligned as described, that has a bug with stretching operators in tables so it also fails to stretch the brackets.

the file at

http://monet.nag.co.uk/~dpc/bm.html

is the same as the attached except that it also has some javascript code inserting objects for Internet explorer /Mathplayer 
which I have removed from the test file, but I mention it as IE/MathPlayer shows the correct display for both cell alignment and stretching.

sorry, correction: 22 should be below 2, 33 and 333 should be below 3

Tested with Safari-MacOSX 6533.18.5, r72896.

Dave,

Did you file a Mozilla bug for the parenthesis-stretching issue?

Not exactly but the mozilla developers confirmed on list that it is was a known issue:

The fix for bug 97401 will implement basic rowspan and columnspan, but operator stretching in an mtable is still currently unimplemented in webkit.
