单元格只包含一个复选框.由于表头行中的文本，它相当宽.如何使复选框(在HTML中带有内联CSS)居中？(我知道)
我试过了
<td>
<input type="checkbox" name="myTextEditBox" value="checked"
style="margin-left:auto; margin-right:auto;">
</td>
但那并不管用.我做错了什么？
更新:这里有一个测试页面.有人能纠正它吗？在HTML中使用CSS内联，这样复选框就会在他们的列中居中？
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Alignment test</title>
</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>
我已经接受了@hristo的答案--这里是内联格式.
<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>
