You can do this:
Header 1Header 2Header 3
Cell 1 Cell 2 Cell 3
Cell 3 Cell 4 Cell 5
Cell 6 Cell 7 Cell 8
Also:
header1header2header3
cell-----1cell-----2cell-----3
cell-----4cell-----5cell-----6
And the obvious third:
header1header2header3
cell--1cell-----1cell--2cell------2cell--3cell-----3
cell--4cell-----4cell--5cell------5cell--6cell-----6
OK, I'm only serious about the first one. Though if you check the code, you need some nifty
s :/
