Question

标题不与列宽对齐。 JsFiddle

我正在使用：

ajax.aspnetcdn.com/ajax/jquery.dataTables/1.9.0/css/jquery.dataTables.css
ajax.aspnetcdn.com/ajax/jquery.dataTables/1.9.0/css/jquery.dataTables_themeroller.css
datatables.net/release-datatables/media/js/jquery.js
datatables.net/release-datatables/media/js/jquery.dataTables.js
datatables.net/release-datatables/extras/FixedColumns/media/js/FixedColumns.js

以下是我正在使用的代码：

JS：

$(document).ready(function() {   
    var aoColumns = [null,null,null,null,null,null,null,null,null,null,null];

    var oTable = $('#example').dataTable( {
        "sScrollX": "100%",
        "sScrollXInner": "150%",
        "bPaginate": false,
        "bAutoWidth": false,
        "aoColumns": aoColumns       
    } );

    var oFC = new FixedColumns( oTable, {
        "iLeftColumns": 4
    } );

    oTable.fnAdjustColumnSizing();
});

HTML：

<body>
   <div class="container">
      <table width="100%" cellpadding="0" cellspacing="0" border="1" id="example">
         <thead>
            <tr>

               <th rowspan="2">Object</th>
               <th rowspan="2">Address</th>
               <th rowspan="2">Count</th>
               <th colspan="7">Availability</th>
            </tr>
            <tr>

Answer 1

问题是由sScrollX滚动条引起的，它为右侧的列添加了额外的水平空间，这就是为什么其他的（没有滚动条）在标题上变短的原因。

如果您对sScrollX行进行注释，则列会正确对齐。

---更新---

要使用js修复宽度，这将起作用：

// *** FIX WIDTHS ON LEFT SIDE ***
var widths = [];

// first fix widths on tbody ...
$('.DTFC_LeftBodyWrapper thead th').each(
    function(){
        $(this).css('width', $(this).width());
    });

// ... now save the actual widths on array
$('.DTFC_LeftBodyWrapper thead th').each(
    function(){ 
        widths.push($(this).width());
    });

// ... and now update widths on thead
$('.DTFC_LeftHeadWrapper thead th').each(
    function(i, val){
        console.log('i:', i, ', width:',  widths[i]);
        $(this).css('width', widths[i]);
    });

我更新了jsfiddle

注意：我还将Count更改为Cnt，因为它在jsfiddle窗口上太长了，导致了额外的宽度问题。

Answer 2

数据表在包含水平填充时会错误计算宽度。

我通过从th中删除填充来解决这个问题，在其中添加一个span，然后将填充添加到span。

即

<style>
th {padding: 0}
th > span {padding: 0 10px}
<style>

像这样更改标记：

<tr>
 <th rowspan="2"><span>Branch</span></th>
 <th rowspan="2"><span>Object</span></th>
</tr>

Answer 3

我可以通过重置th的边距并填充为零来解决它：

th {
  padding: 0 !important;
  margin: 0 !important;
}

固定列标题宽度与主体列宽不匹配
