javascript - datatables.net 中的复杂 header

Question

我正在使用 datatables.net 的表格插件。我遇到了复杂标题列的问题，并且在使用时出现以下错误。

Uncaught TypeError: Cannot call method 'fnSetData' of undefined at jquery.dataTables.js line 820

这段html代码(其实这是一个模板)

    <!-- BEGIN:main -->
<table id='myTable' style='width: 100%'>
    <thead>
        <tr>
            <th rowspan="2"></th>
            <th colspan="4">Contract Details</th>
            <th colspan="4">Delivery</th>
            <th rowspan="2">Basis Terminal Month</th>
            <th colspan="5">Fixed</th>
            <th colspan="4">Unfixed</th>
            <th colspan="3">Trigger</th>
            <th colspan="2">Payment</th>
            <th colspan="2" rowspan="2"></th>
        </tr>
        <tr>
            <th>Contract Ref</th>
            <th>Supplier/Buyer</th>
            <th>Grade</th>
            <th>Days Pending</th>
            <th>Tons</th>

            <th>Outright Exposure FOB</th>
            <th>Tons</th>
            <th>Contract FOB Diff</th>
            <th>Mark To Market FOB Diff</th>
            <th>Differential Exposure FOB</th>
            <th>Strike Price</th>
            <th>Variance</th>
            <th>Days</th>
            <th>Due Date</th>
            <th>Days Late</th>
        </tr>
    </thead>
    <tbody>
        <!-- BEGIN:row -->
        <tr id="row_{id}">
            <td>{count}</td>
            <td>{ref_number}</td>

            <td  class="formatNumber alignRight">{pending_tons}</td>
            <td><input type="checkbox" id="rd_{id1}" value="{delivery_status}" {checked}/></td>
            <td class="alignCenter">{terminal_month}</td>

            <td  class="formatNumber alignRight">{variance}</td>
            <td  class="formatNumber alignRight">{trigger_days}</td>
            <td>{payment_due_date}</td>
            <td  class="formatNumber alignRight">{payment_days_late}</td>
            <td><input type="button" value="Detail" onclick="ContractDetail('{id2}')"/></td>
            <td><input type="button" value="Traffic" onclick="trafficMovement('{id3}')"/></td>
        </tr>
        <!-- END:row -->
    </tbody>
</table>
<input type="hidden" id="action" name="action" value=""/>
<input type="hidden" id="contract_id" name="contract_id" value=""/>
<!-- END:main -->

这是我调用数据表的javascript

$(document).ready(function() {
    $("#myTable").dataTable();
});

我不知道是什么问题，我在 datatables.net 上看到他们说它通过调用 datatable() 支持复杂的标题列。我认为我的问题出在 html 代码上。

Answer 1

问题出在您为按钮添加的最后两列的标题中。您将其声明为 rowspan="2" 和 colspan="2" 并且 DataTables 将其解释为单个列。

只需更改

<th colspan="2" rowspan="2"></th>

成为:

<th rowspan="2"></th>
<th rowspan="2"></th>

你会很高兴的。
