本文实例讲述了js动态修改表格行colspan列跨度的方法。分享给大家供大家参考。具体如下：
<!DOCTYPE html>
<html>
<head>
<script>
function setColSpan()
{
var x=document.getElementById('myTable').rows[0].cells;
x[0].colSpan="2";
x[1].colSpan="6";
}
</script>
</head>
<body>
<table id="myTable" border="1">
<tr>
<td colspan="4">cell 1</td>
<td colspan="4">cell 2</td>
</tr>
<tr>
<td>cell 3</td>
<td>cell 4</td>
<td>cell 5</td>
<td>cell 6</td>
<td>cell 7</td>
<td>cell 8</td>
<td>cell 9</td>
<td>cell 10</td>
</tr>
</table>
<form>
<input type="button" onclick="setColSpan()"
value="Change colspan">
</form>
</body>
</html>希望本文所述对大家的javascript程序设计有所帮助。
