Number of Columns
You can set the number of columns in this box, as well as by pressing the buttons. It is possible to have more than three columns if you set them here. You can type in the box or use the arrows to increase or decrease the number.
Space after Column
Set the space that AbiWord leaves between the end of a column and the following text. You can type in the box or use the arrow buttons to increase and decrease the setting.
Set the maximum height of a single column. If the text will not fit in this space, AbiWord starts a new column. This may mean moving to the next column across the page, or starting a new column below the one that is full. If a new column is started below the current column, the space specified in that option will be left.
If this is set to 0.0, there is no maximum height. Columns fill the whole page before starting a new column.
