First, I declare that there are many practices to introduce one of them.
<HTML>
<Body>
<Table width = "100%" align = "center" border = 0>
<Tr>
<Table width = "100%" border = 1>
<Tr>
& Lt; TD width = "50%" & gt;
Biaoti1321
</TD>
& Lt; TD width = "50%" & gt;
Biaoti2321321
</TD>
<TD>
& Nbsp;
</TD>
</Tr>
</Table>
</Tr>
<Tr>
<TD align = "center" width = "100%">
<Div style = "overflow-Y: auto; width: 100%; Height: 100px">
<Table width = "100%" border = 1>
<Tr>
<TD> 111 </TD>
<TD> 111 </TD>
</Tr>
<Tr>
<TD> 111 </TD>
<TD> 111 </TD>
</Tr>
<Tr>
<TD> 111 </TD>
<TD> 111 </TD>
</Tr>
<Tr>
<TD> 111 </TD>
<TD> 111 </TD>
</Tr>
<Tr>
<TD> 111 </TD>
<TD> 111 </TD>
</Tr>
<Tr>
<TD> 111 </TD>
<TD> 111 </TD>
</Tr>
<Tr>
<TD> 111 </TD>
<TD> 111 </TD>
</Tr>
<Tr>
<TD> 111 </TD>
<TD> 111 </TD>
</Tr>
<Tr>
<TD> 111 </TD>
<TD> 111 </TD>
</Tr>
</Table>
</Div>
</TD>
</Tr>
</Table>
</Body>
</Html>
The specific idea is that this is a big table, and the header and the result field each have a table,
The header has n headers, which must be divided into n + 1 TD. The total width of the First n td is 100%, and the last one is used to give the scroll bar position, otherwise, it is difficult to align with the following table.
The following result body table must be included in the Div. Set the length of TD to be consistent with the length of TD above.
