You can change the alignment of paragraphs in a text box, table cell, shape, or column so that text is aligned to the left or right border, centered, or aligned on both left and right (justified).
First you must select the text or text box containing text you want to align.
Click the Alignment buttons in the format bar.
Click Inspector in the toolbar, click the Text button, and then click Text. Click one of the five horizontal alignment buttons, located to the right of the color well.
Choose Format > Text > Align Left, Center, Align Right, Justify, or Auto Align Table Cell
From left to right, the buttons in the format bar and Text inspector have the following effects:
The first four alignment buttons are available on the format bar when text is selected. The fifth horizontal alignment button is also available on the format bar when a table cell is selected.
