A sample 4 x 3 table
1 2 3
English <th> one two three
Spanish <td><b> uno dos tres
French <td> un deux troi
this is a double row with width spec one two three
a b c
Notice there appears to be no difference between TD+bold and TH, but see that actually "Spanish" is left justified, instead of centered.

Also note the colored border around "deux" which only works in IE.

Now for an example of an areamap (2 columns, 1st col has 2 rows)
