To insert a new table, select Insert from the Content Authoring Ribbon Tab. A dialog will be displayed prompting you to specify the number of initial rows and columns and optionally select a style to apply to the new table and cells.

To select an entire row, position your mouse over the left-most border at the edge of the row. The cursor will change to a right pointing horizontal arrow. Once you have this cursor, click once to select the row. To select multiple rows, hold down Control as you click to preserve existing settings, or hold down Shift to select all rows between the currently selected row and the clicked row.

Selecting columns is very similar to selecting rows, the difference being you hover your mouse on the top-most border at the upper edge of the column. The mouse cursor will change to a downwards pointing vertical arrow. Click the highlight the column, or use the Control or Shift keys as mentioned above to selected multiple columns.

To select a cell, move the mouse to the lower portion of the left-most cell border. The mouse cursor will change to an up-right pointing arrow, click to select the cell. As with other selection methods, you can use Control and Shift to select multiple cells.
