Word also offers built_in table templates that enable you to insert pre_formatted "Quick Tables" into your documents. To insert a table using one of Word's templates, choose Insert > Table > Quick Tables and choose the template you'd like to use from the gallery. When you click on the template, Word will insert the pre_formatted table of your choice.
Alternately, you may select an entire row by moving your mouse to the left_most cell in a row. When the cursor changes to an arrow, click the mouse and the entire row will be selected. You may select an entire column by moving your mouse to the top_most cell in a column. When the mouse pointer changes to an arrow, click the column and all cells in it will be selected. Once the desired cells have been selected, you may apply formatting changes to your selections as desired.
