Change the size of a column or row: Move the pointer onto a gridline or border, and when the pointer changes into a double-headed arrow, start dragging.
You can also go to the (Table Tools) Layout tab and change the measurements in the Cell Size boxes to change the width of a column or the height of a row. The measurements affect entire columns or rows, not individual cells.
A table: Drag a selection handle on a side or corner. You can also go to the Layout tab, click the Table Size button (if necessary), and enter inch measurements in the Height and Width text boxes.
