Word comes with a table editor that you can use to create simple or complex tables. If you find yourself spending a lot of time working on a table to have it fit your specific needs and formatted exactly the way you like, you may want to copy the table to a new location so you can use the same layout more than once. Why waste time reinventing the wheel right? After you copy your table, you will t want to erase the contents of the table so that you can key in your new text.
My quick and easy way to erase the data in my table, is to select the entire table and then hit the Delete key. Your information in the table is cleared, but the structure of your table remains.
Please note though, that you must press the Delete key. If, instead, you press Backspace while the whole table is selected, Word will delete your entire table, not just the content.
