Format a table in OneNote for the web

After you insert a table on a page in OneNote for the web, you can select it, modify it, and format it to change the way it looks.

In OneNote for the web, make sure your pointer is within the table row or column you want to format. The Table Tools > Layout tab will appear.
Click the Layout tab to reveal the ribbon groups, and then in the Select ribbon group, click or tap what you want to select in the table to modify.
Do any of the following:
- To delete rows or columns from your table, use the commands in the Delete ribbon group.
- To add additional rows or columns to your table, use the commands in the Insert ribbon group.
- To apply or remove table borders to parts of your table, use the commands in the Borders ribbon group.
- To align the text within the cells of your table, use the commands in the Alignment ribbon group.
- To apply a background color to selected cells in your table, click or tap Shading in the ribbon, and then select a shade.
- To adjust the width of a column, hover the pointer over an edge of a column until you see the double-headed arrow, and then drag the edge.
  
  You cannot set column widths using number values.

Tip: Commands in the Select, Insert, Delete, and Shading ribbon groups can also be applied by right-clicking within a table.
