Change part of table column size

Question

I would like to know if there is a way, that I can resize part of a column, while keeping the rest the same size. Such that I would get this:

Column
___|
___|
___|
_______|
_______|
_______|

I have included my project below as tex and an image. The cells in want to change is Column 1, row 1 to Column 1, row 9.

Answer 1

I think you mean something like:

In which case it's easiest to insert extra columns and the use \multicolumn to merge columns in the two halves. I disabled the colours as you didn't supply any code defining them and I don't think they are related to the question.
