If you’d like to organize information in your notes, you can create a table.
Click Insert > Table, and then move the mouse over the grid to select the size of the table you want.
Click the lower-right highlighted cell.
Note: When you add a new table on a page, OneNote reveals the hidden Table Tools tab on the ribbon. Here, you can select and format the table. To return to these tools again at any time, click anywhere within a table on a notes page. You can also access most of the table commands by right-clicking any table cell and then clicking the Table command.
