The easiest way to resize rows and columns is to drag their borders. But you can also select one or more cells and use menu commands to make their rows or columns the same height or width.
If you want to specify exact dimensions for row height or column width, use the Table inspector.
If the cell content is too large for its cell, a clipping indicator appears as a plus sign (+) inside a square in the lower-right corner of the cell. In the Table inspector, you can set automatic cell resizing to fit the content.
To resize a single row, drag the bottom border of the row up or down.
To resize one column, drag the a column border right or left.
To make all rows the same size, select the table and choose Format > Table > Distribute Rows Evenly.
To make several rows the same size, select one or more cells in the rows and choose Table > Distribute Rows Evenly. The rows don't have to be adjacent.
To make all columns the same size, choose Format > Table > Distribute Columns Evenly.
