You can easily apply styles to tables. There are several predefined styles to choose from, listed in the Styles pane (refer to Figure 1).
To change the style of a table, select the table (either on the sheet or in the Sheets pane) and click the style you wish to use. You can also Control-click or select the down arrow icon that appears when you hover over a style to select options.
Using the pop-up menu, you can create a new style based on the selected table, rename or delete the style, set the style as the default for tables in the document, or select "Clear and Apply Style" to remove all style information within a table (including information applied to individual cells) and use the selected style.
To modify a style, select the entire table (or specific rows, columns, or cells) and then use the formatting options in the contextual toolbar to adjust them. You can choose, for example, whether to display header and footer rows (and header columns), whether to display cell borders (and how they are displayed), and the fill or background color of the cell or table.
To set advanced options, click the Inspector button in the toolbar and choose the Table Inspector tab. Using these Advanced options, you can add gradient and image fills to your table; you can, for example, apply a fill to alternating rows to make reading data easier on the eye. This tab also lets you specify cell height and width (which can also be done by selecting the space between rows and columns and dragging). You can also change the name of the table in the Advanced tab (or just double-click the table in the Sheets panel) and split or merge select cells.
