    for($row=1;$row<=6;$row++){

        echo "<tr>";

        for($col=1;$col<=6;$col++) {

            $total=$row+$col;

            $i=1;

            if($total%2==0) {

                echo "<td height=50px width=50px bgcolor=#FFFFFF align='center'></td>";

            } else {

只需将行和列相乘即可。for($row=1;$row<=6;$row++){&nbsp; &nbsp; echo "<tr>";&nbsp; &nbsp; for($col=1;$col<=6;$col++) {&nbsp; &nbsp; &nbsp; &nbsp; $total=$row+$col;&nbsp; &nbsp; &nbsp; &nbsp; $i=1;&nbsp; &nbsp; &nbsp; &nbsp; if($total%2==0) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; echo "<td height=50px width=50px bgcolor=#FFFFFF align='center'>".$row*$col."</td>";&nbsp; &nbsp; &nbsp; &nbsp; } else {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; echo "<td height=50px width=50px bgcolor=#000000 style='color:white; text-align:center;'>".$row*$col."</td>";&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; echo "</tr>";}
