In the Columns dialog box, you can pick a Preset and, if needed, provide more specific values for the number and spacing of columns.
Choosing one of the layouts under Presets changes the number of columns and all the column width and spacing options at once - if you find a Preset that's just right, select it, and then select OK to close the dialog box and apply the changes.
Or, enter a number for Number of columns and then adjust the settings under Width and spacing to choose your column width and the spacing between columns.
Insert a column break to control how text flows between columns. For example, insert a column break to end a paragraph in one column and start a new paragraph at the top of the next column.
If your document has more than one section, a column layout will only be applied to the current section.
