Re: colspan doubt

All you need to know is that column boundaries extend straight from top
to bottom -- they do not move (CSS notwithstanding). So you can have:

  +-------+-------+-------+
  |  =1   |  =1   |  =1   |  (33%, 34%, 33%)
  +-------+-------+-------+
  |  =1   |      =2       |  (33%, 67%)
  +-------+-------+-------+
  |  =1   |  =1   |  =1   |
  +-------+-------+-------+
but you can NOT have:
  +-------+-------+-------+
  |  =1   |  =1   |  =1   |
  +-------+---+---+-------+
  |   =1.5    |   =1.5    | <--no no no, sorry, can't do that!
  +-------+---+---+-------+
  |  =1   |  =1   |  =1   |
  +-------+-------+-------+
unless you actually do it like this:
  +-------+---+---+-------+
  |  =1   |  =2   |  =1   |  (33%, 17%+17%=34%, 33%)
  +-------+---+---+-------+
  |    =2     |     =2    |  (50%, 50%)
  +-------+---+---+-------+
  |  =1   |  =2   |  =1   |
  +-------+---+---+-------+

To put it another way, you can only have INTEGER colspans (and rowspans).
