Description

Use the cellpadding attribute to create some space around the contents of table cells (in th and td elements). The effect of this attribute’s application won’t be immediately obvious unless you’ve also set a border attribute for the table, as Figure 1 reveals.

The cellpadding attribute is similar to the cellspacing attribute, which is used to create space between and outside of the table cells.

</table>

Value
