Last column in table does not size as configure

  • Working with XE7 and WPTools 7.21
    I am creating a table with 10 columns as follows

    I see that the last column does not size to 1.5 centimeters as the others, but expands to the full available width of the page.

    I do not know if there is some parameter for telling the global with of the table, and that it does not expand to the full width of the paper.
