There ara two ways:
1. Left click with your mouse on the division line between the columns
at the top of the spreadsheet and drag it to the width you want. All
the cells in that column will be the same width, but not the rest of
the page.

2. Highlight the cell and the one next to it.. Go to Format/ Cells/
Alignment and check both the Merge Cells block and the Wrap Text block,
then OK. Repeat as necessary, or include more cells, or use method #1
also. ed
