Automatically add a new row when reaches the last row (word 2010)

I made a table in WORD 2010 and put 3 rows in it.
What i want is that if a user reaches the last row (no matter what cell in the last row), its automatically add a new row.
Or a Button when pressed is adding a row.

I hope this is possible and thank you very much.

p.s, sorry about my english if i have spelling mistakes

Word automatically adds a new table row when you press the tab key from the end of the last cell in the table.

What macropod is trying to tell you is that it is perhaps better to train your users to use the Tab key when in the last table cell to add a row rather than alter how the application works in one document.

Making a change so a row is added when the last row is entered might be possible, but it would not be trivial and could have side-effects that would be undesirable.
