Your php code in your example creates a row in your HTML table for every row in your result set from MySQL. Change that code to create columns. php is excellent for this sort of thing; it manipulates text and HTML tables are just text.

To do this you need to, actually, create two rows. One is the header row and the other the detail row.

Try something like this. Please notice that this code is not debugged.

$hdr = "";
$dat = "";

while($row = mysqli_fetch_object($res)) {
   $hdr = $hdr + "<td>" + $row->Category + "</td>";
   $dat = $dat + "<td>" + $row->Value    + "</td>";
}
echo "<tr>" + $hdr + "</tr>";
echo "<tr>" + $dat + "</tr>";

Do you see how $hdr = $hdr + table cell accumulates a bunch of table cells for each data item, containing the Category values in your result set? Likewise, $dat = $dat + table cell accumulates a bunch of table cells for each data item.

Sorry to say I don't understand Area_A and the other area items in your question, so I haven't tried to program those.
