Can we have a table within a table??
Let's try. Start with little Ed. 

<TABLE BORDER=3>
<TR>
<TD>Ed</TD>
</TR>
</TABLE>

Ed

Make the table a fuzz bigger. 

<TABLE BORDER=3 WIDTH=200 HEIGHT=100>
<TR>
<TD>Ed</TD>
</TR>
</TABLE>

Ed

Replace Ed with a complete "little Ed" table 

<TABLE BORDER=3 WIDTH=200 HEIGHT=100>
<TR>
<TD>

<TABLE BORDER=3>
<TR>
<TD>Ed</TD>
</TR>
</TABLE>

</TD>
</TR>
</TABLE>

Ed

Well, howa bout that!

Our table can also be centered very easily. 

<CENTER>
<TABLE BORDER=3 WIDTH=200 HEIGHT=100>
<TR>
<TD>

<TABLE BORDER=3>
<TR>
<TD>Ed</TD>
</TR>
</TABLE>

</TD>
</TR>
</TABLE>
</CENTER>
