What happens when you place the cursor in the last cell of a table in an MS Word document and press the TAB key?

Explanation
In MS Word, pressing the TAB key normally moves the cursor to the next cell in a table.
When the cursor is already in the last cell of the last row, there is no "next cell" available.
To handle this, Word automatically creates a new row at the end of the table and places the cursor in the first cell of that new row.
This feature makes it easier to continue adding data without manually inserting rows.
Why not the other options?
Row deleted → Pressing TAB never deletes rows.
Rows swapped → There is no function in Word that swaps rows with TAB.
Row added at the beginning → TAB does not insert rows at the start; it only extends the table at the end.
