Hi Grace,
You can correct it by double clicking on the boundary line between the
row numbers. There are several causes.
- manually setting the row height Format, row, height or by
moving that line between the row numbers to adjust height.
- merged cells will affect what was an automatic adjustment.
The do the entire worksheet, you select all cells Ctrl+A then
or for a selection of rows
you can double click or move any of those boundary lines between
selected rows.
