Cell Padding (NISO JATS table model)
Amount of space, measured in pixels, between the border of a cell and the contents of a table cell. (This attribute is based on and intended to be converted easily to the XHTML cellpadding attribute.)
Best Practice: Although the Tag Set can enforce only that this attribute contain any text, numbers, or special characters, best practice is to constrain this value to a counting number (positive integer).
Used on Element: <table>
|Counting number||Thickness, measured in pixels, of the cell padding.|
|Restriction||@cellpadding is an optional attribute; there is no XML default. The typical browser default is “1” pixel.|
