现在我能够正确获取标题和数据，但这会让页面感到不安......页面的宽度正在扩展。
答案 0 :(得分：0)
如果我理解正确，你实际上有2张桌子。一个包含表头（让我们称之为headerTable）和一个包含表数据（让我们称之为dataTable）。
如果是这种情况，那么你将不得不编写一些自定义的javascript逻辑，它循环遍历dataTable中第一行的单元格。检索每个单元格的实际宽度，并在headerTable的相应标题单元格中设置此宽度。
这样的事情：
function resizeHeaders(dataTableFirstRowCells, headerTableCells)
{
for (var i=0; i<dataTableFirstRowCells.length; i++)
{
var cell = $(headers[i]);
var renderedWidth = cell.getWidth(); // 'getWidth' might be different depending on which (and if) js framework you use)
$(headerTableCells[i]).setWidth(renderedWidth);
}
}
