How much are you trying to change it by? Sometimes "snap to grid" will bite
you. You can override the grid by pressing Alt while dragging.

I have inserted a table with three columns. Now I want to change the width
of
the columns, but I can't do it with the mouse. I get this mouse pointer
looking like you are able to draw the column border, but when I press and
hold down the mouse button and try to drag the border nothing happens.
Why?
