jQuery : Merge column of table

Question

我想合并下一个表格的最后一列的单元格具有相同的文本:

我有这段代码，但它会检查相邻行的单元格:

<script language="javascript" type="text/javascript">
    $(document).ready(function () {

        $('#sample_1 tbody tr:nth-child(4) td:nth-child(4)').each(function(){
            alert( $(this).text());

            var colSpan=1;
            while( $(this).text() == $(this).next().text() ){

                $(this).next().remove();
                colSpan++;
            }
            $(this).attr('colSpan',colSpan);
        });
    });
</script>

这是表格 HTML 的代码源:

<table class="table table-striped table-bordered dataTable TF" id="sample_1" aria-describedby="sample_1_info">
    <tbody role="alert" aria-live="polite" aria-relevant="all">
        <tr class="fltrow">
            <td colspan="4">
                <input id="flt0_sample_1" type="text" ct="0" class="single_flt">
            </td>
        </tr>
        <tr class="gradeX odd">
        </tr>
        <tr role="row">

这不是最优雅的解决方案，但它确实有效。

我在您的第 4 列中添加了一个名为“heure”的类

<td class="heure">11:00</td>

以及对您的 JS 的以下更改

<script language="javascript" type="text/javascript">
    $(document).ready(function () {

        var topMatchTd;
        var previousValue = "";
        var rowSpan = 1;

        $('.heure').each(function(){

            if($(this).text() == previousValue)
            {
              rowSpan++;
              $(topMatchTd).attr('rowspan',rowSpan);
              $(this).remove();
            }
            else
            {
              topMatchTd = $(this);
              rowSpan = 1;
            }

            previousValue = $(this).text();
        });
    });
</script>
