First lets make it look more like a table and give it a border.
<TABLE BORDER=1>
<TR>
<TD>Ed</TD>
</TR>
</TABLE>
Ed
IMPORTANT NOTE: Whenever you make a change to your document, just save it, then hit the Refresh/Reload button on your browser. In many instances just hitting the refresh button doesn't quite do the trick. In that case...
Internet Explorer users: Click Refresh while holding down the CTRL key.
Netscape users: Click Reload while holding down the SHIFT key.
How about a bigger border?
<TABLE BORDER=5>
<TR>
<TD>Ed</TD>
</TR>
</TABLE>
Ed
How about a HUGE border?
<TABLE BORDER=25>
<TR>
<TD>Ed</TD>
</TR>
</TABLE>
Ed
How about NO border?
<TABLE BORDER=0>
<TR>
<TD>Ed</TD>
</TR>
</TABLE>
Ed
As you can see, the default is (usually) no border.
Let's stick with a modest border for now.
<TABLE BORDER=3>
<TR>
<TD>Ed</TD>
</TR>
</TABLE>
Ed
When no sizes are specified the table is only as big as it needs to be.
<TABLE BORDER=3>
<TR>
<TD>Ed, Rick and Tom</TD>
</TR>
</TABLE>
