If a cell isn’t wide enough to display its text on one line, you can wrap the text so it appears on multiple lines in the cell.
Do any of the following:
Wrap or unwrap text in a single cell: Control-click the cell. In the shortcut menu, a checkmark appears next to Wrap Text when it’s selected. To unwrap text, deselect it.
Wrap or unwrap text for a row, column, or the entire table: Select the row or column, or select the table. In the sidebar on the right, click the Text tab, then click the Style button near the top of the sidebar. A checkmark appears in the “Wrap text in cell” checkbox when it’s selected. To unwrap text, deselect the checkbox.
If you don’t see a sidebar, or the sidebar doesn’t have a Text tab, click
in the toolbar.
