Cell Spacing (NISO JATS table model)
Width of space between cells in a table. (This attribute is based on and intended to be converted easily to the XHMTL cellspacing 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 space between cells in a table.|
|Restriction||@cellspacing is an optional attribute; there is no default.|
