To create a table from scratch:

Select Table > Insert > Table from the main menu. Select the number of rows and columns and click OK. Select the default Autofit Behavior. Dont worry about making mistakes. You can easily change the number of both the rows and columns later on.

Or, click the Insert Table icon on the Toolbar. Drag your cursor to determine the number of rows and columns. Dont worry about making mistakes. You can easily change the number of both the rows and columns later on.

To insert a row or column to the right or left of a row or column:

Place your cursor in the row or column (any cell).

Select Table > Insert > Columns to the Left (or, Columns to the Right, or Rows Above, or Rows Below).

To merge 2 cells, select the cells with your cursor and then select Table > Merge Cells from the main menu.

To split a cell into multiple cells, place your cursor inside the cell. Then select Table > Split Cells from the main menu. Select the number of rows and columns you want to see after the split. Click OK.

If you have a long table that will straddle across multiple pages, and if you need to see your column headers on every page, then select Table > Heading Rows Repeat.

If you need to convert your table into text, select your table (the most guaranteed way especially if you have a huge table -- is by selecting Table > Select > Table from the main menu). Then select Table > Convert > Table to Text.

Usually selecting Tabs as a text separator is a sufficient choice but you can select other separators as well in the Convert Table to Text dialog box.

Click OK when finished.
