向动态表添加行号

Question

如何为动态生成的表添加行号或序列号？ 这是我的代码。

echo"<table>";
for($tr=1;$tr<=$rows;$tr++){

    echo "<tr>";
    for($td=1;$td<=$cols;$td++){
     //  echo "<td>row: ".$tr." column: ".$td."</td>";

        echo "<td><input type='text' name='bhk'></td>";

    }
    echo "</tr>";
}

echo "</table>";

Answer 1

试试这个

echo"<table>";
for($tr=1;$tr<=$rows;$tr++){

    echo "<tr id=".$tr.">";
    for($td=1;$td<=$cols;$td++){
     //  echo "<td>row: ".$tr." column: ".$td."</td>";

        echo "<td><input type='text' name='bhk'></td>";

    }
    echo "</tr>";
}

echo "</table>";
