In general, use the same methods to format text in a table that you would use to format text that’s not in a table.
When the insertion point is in a table, pressing Tab moves the insertion point to the next cell. However, you can insert a tab within a table cell. Use the Tabs panel to define tab settings in the table. Tab settings affect the paragraph in which the insertion point is placed.
To change tab settings, select the columns or cells you want to affect, choose Type > Tabs to display the Tabs panel, and then adjust tab settings.
