lyx_mirror/src/insets/insettabular.C
John Levon 92782a861e back out tall table speedup. It broke column width setting. 
I have no idea why. calculate_dimensions_of_cells must surely be called on the
SET_PWIDTH, but for some reason it doesn't resize the column despite resizing
the cell widths.

This is the sort of "fun" that changing anything in the table
code incurs. It sucks mightily :(
