Document tables can be edited in several different ways. The table can have rows/columns inserted, deleted, merged, and customized. The majority of customization options are presented when you place your cursor in a table and the formatting icons will appear at above or below the table (depending on the tables position on the page/screen):
Columns
To add a column, place your cursor inside a table cell and use the column settings button to add or remove columns.
Rows
To add a row, place your cursor inside a table cell and use the row settings button to add or remove rows. You can also specify a row as the header row (which will update its formatting). You can change the formatting of the header row using the "Cell Properties" as noted below.
Table Properties
Table properties will permit you to set a border for the outside of the table, a background color for all cells, and other adjustments. These changes will be applied to the table as a whole.
Cell Properties
Cell properties permits you to set a border, background color and other adjustments for a specific cell(s) in the table. You can apply the changes to multiple cells at once by highlighting multiple cells before clicking on cell properties.
