## Examples

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

<TABLE ID="oID_1" RULES="cols">
<THEAD>
<TR>
<TD>EST</TD><TD>1am</TD><TD>8pm</TD>
</TR>
</THEAD>
<TR>
<TD>CST</TD><TD>2am</TD><TD>9pm</TD>
</TR>
<TR>
<TD>MST</TD><TD>3am</TD><TD>10pm</TD>
</TR>
<TFOOT>
<TR>
<TD>PST</TD><TD>4am</TD><TD>11pm</TD>
</TR>
</TFOOT>
</TABLE>
<P>
<BUTTON onclick="oID_1.rules=''">No borders</BUTTON>
<BUTTON onclick="oID_1.rules='none'">Exterior border</BUTTON>
<BUTTON onclick="oID_1.rules='all'">All borders</BUTTON><BR>
<BUTTON onclick="oID_1.rules='cols'">Column borders</BUTTON>
<BUTTON onclick="oID_1.rules='groups'">Groups borders</BUTTON>
<BUTTON onclick="oID_1.rules='rows'">Table row borders</BUTTON>
</P>

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>
</TR>
</THEAD>
<TR>
<TD>CST</TD><TD>2am</TD><TD>9pm</TD>
</TR>
<TR>
<TD>MST</TD><TD>3am</TD><TD>10pm</TD>
</TR>
<TFOOT>
<TR>
<TD>PST</TD><TD>4am</TD><TD>11pm</TD>
</TR>
</TFOOT>
</TABLE>
<P>
<BUTTON onclick="oID_1.rules=''">No borders</BUTTON>
<BUTTON onclick="oID_1.rules='none'">Exterior border</BUTTON>
<BUTTON onclick="oID_1.rules='all'">All borders</BUTTON><BR>
<BUTTON onclick="oID_1.rules='cols'">Column borders</BUTTON>
<BUTTON onclick="oID_1.rules='groups'">Groups borders</BUTTON>
<BUTTON onclick="oID_1.rules='rows'">Table row borders</BUTTON>
</P>
