These tests are for CSS 2.1 issue 26, about the proposal split between my first and second message and Bruno's response.

First, we need to see if the browser implements baseline alignment of cells. If it does, the baselines of these cells should be aligned:

Cell 1

Cell 2

Cell 3

Cell 4

If the baselines of the above cells don't line up, then the remaining tests are meaningless.

Second, we need to check that the height property on table cells does not increase the height of the cell box. This means that the following text should be centered within the table's border:

Third, if both those are as expected, we can look at a local version of Bruno's testcase (best placed in the same document so we know we're in the same compatibility mode):

Are all of these tables the same height?
