如何在表格单元格中居中放置复选框?

css

该单元格仅包含一个复选框。由于表标题行中的文本,所以它很宽。如何将复选框居中(在HTML中包含内联CSS?(我知道))

我试过了

 <td>
      <input type="checkbox" name="myTextEditBox" value="checked" 
      style="margin-left:auto; margin-right:auto;">
 </td>

但这没用。我究竟做错了什么?


更新:这是一个测试页。有人可以更正它吗(在HTML中使用CSS内联),以使复选框位于其列的中心?

<head>

<body>

<table style="empty-cells:hide; margin-left:auto; margin-right:auto;" border="1"   cellpadding="1" cellspacing="1">

  <tr>
    <th>Search?</th><th>Field</th><th colspan="2">Search criteria</th><th>Include in report?<br></th>
  </tr>

  <tr>
    <td>
        <input type="checkbox" name="query_myTextEditBox" style="text-align:center; vertical-align: middle;">    
    </td>

    <td>
      myTextEditBox
    </td>

    <td>
       <select size ="1" name="myTextEditBox_compare_operator">
        <option value="=">equals</option>
        <option value="<>">does not equal</option>
       </select>
    </td>

    <td>
      <input type="text" name="myTextEditBox_compare_value">
    </td>

    <td>
      <input type="checkbox" name="report_myTextEditBox" value="checked" style="text-align:center; vertical-align: middle;">
    </td>

  </tr>

</table>


</body>
</html>

我已经接受@Hristo的回答-这就是内联格式…

<table style="empty-cells:hide;" border="1"   cellpadding="1" cellspacing="1">

    <tr>
        <th>Search?</th><th>Field</th><th colspan="2">Search criteria</th><th>Include in report?<br></th>
    </tr>

    <tr>
        <td style="text-align: center; vertical-align: middle;">
            <input type="checkbox" name="query_myTextEditBox">    
        </td>

        <td>
            myTextEditBox
        </td>

        <td>
            <select size ="1" name="myTextEditBox_compare_operator">
                <option value="=">equals</option>
                <option value="<>">does not equal</option>
            </select>
        </td>

        <td>
            <input type="text" name="myTextEditBox_compare_value">
        </td>

        <td style="text-align: center; vertical-align: middle;">
            <input type="checkbox" name="report_myTextEditBox" value="checked">
        </td>

    </tr>

</table>

HTML

<table>
  <tr>
    <td>
      <input type="checkbox" name="myTextEditBox" value="checked" /> checkbox
    </td>
  </tr>
</table>

CSS

td {
  text-align: center; /* center checkbox horizontally */
  vertical-align: middle; /* center checkbox vertically */
}
table {
  border: 1px solid;
  width: 200px;
}
tr {
  height: 80px;   
}

我希望这有帮助。
