while($row = mysql_fetch_array($result))
  {


  echo "<tr>"; 

    echo "<td>" . $row['app_file_id'] . "</td>";

    echo"<td>". $row['Principal Repaid'] ."</td>";
    echo"<td>". $row['avg(app_amnt_owed)'] ."</td>";    
    echo"<td>". $row['SUM(r.receipt_on_interest)'] ."</td>";

推荐答案

PHP不会将事件发送到浏览器.您可以使用Javascript做到这一点.

PHP doesn't send Events to a Browser. You can do that with Javascript.

<input type="button" onclick="window.print()" value="Print Table" />

要隐藏所有其他不想打印的东西，请将其添加到html中:

To hide all the other Stuff you don't want to print add this to your html:

<style media="printer">
      .noprint * {
          display:none;
      }

然后将css类noprint分配给您不想打印的父元素.

And assign the css class noprint to the parent element you don't want to get printed.

未经测试，但这也可以工作:

Not tested but this could work too:

body {
    visibility: hidden;
}
.printthis {
    visibility: visible;
}

并为您的表提供类printthis，这样就只会打印该表.

And give your table the class printthis and so only the table gets printed.
