表格宽度的自由拖动
html中表格table中，每列宽度自动拖动的实现方法
1、引入两个js文件：jquery.js和colResizable-1.3.min.js，具体见附件
<script src="jquery.js"></script><script src="colResizable-1.3.min.js"></script>
<script type="text/javascript">$(function(){var onSampleResized = function(e){var columns = $(e.currentTarget).find("th");};$("#sample2").colResizable({liveDrag:true, gripInnerHtml:"<div class='grip'></div>", draggingClass:"dragging", onResize:onSampleResized});});</script><table id="sample2" width="100%" border="1" cellpadding="0" cellspacing="0"><tr><th>header</th><th>header</th><th>header</th></tr><tr><td class="left">cell</td><td>cell</td><td class="right">cell</td></tr><tr><td class="left">cell</td><td>cell</td><td class="right">cell</td></tr><tr><td class="left bottom">cell</td><td class="bottom">cell</td><td class="bottom right">cell</td></tr></table>
