Once you create a table you can edit its properties by right clicking on the table (in the advanced content editor) and selecting "Table Properties". Right clicking a table is also how you can add and delete cells, columns and rows.
To create alternating row colors go into the "Table Properties" click the "Advanced" tab and in the text field called "Style Sheet Classes" enter the tag "table_alternating_rows".
