Possible Values

The value none turns off only the interior borders. To turn off the table borders, set the rules property to '', or omit the RULES attribute from the table object.

Examples

This example initially sets the RULES attribute on the table, and then uses the rules property to dynamically change the table borders.

In this example, the table object contains the RULES attribute set to cols and the border attribute set to an empty string (""). This example demonstrates that if the RULES attribute is set to an empty string (""), the border attribute will cause the table to show all borders, trumping the RULES attribute.

<TABLE ID="oID_1" BORDER="" RULES="cols">
<THEAD>
<TR>
<TD>EST</TD><TD>1am</TD><TD>8pm</TD>
