如何只获取带有值的html表行列？

Question

我想知道是否有更简单的方法只获取带有值的html表行列

这是一个示例表格图像

这就是我希望它成为

＆＃13;

＆＃13;

 <table id="tblPayslipApproval" cellspacing="0" border="0">
    <tbody>
    <tr class="tr-border-full">
      <td style="min-width:50px">EARNINGS</td>
      <td style="min-width:50px"></td>
      <td style="min-width:50px" class="td-border-right"></td>
      <td style="min-width:50px" align="center" colspan="3" class="td-border-right">DEDUCTIONS</td>
      <td style="min-width:50px" align="center" colspan="3" class="td-border-right">LOAN BALANCES</td>
    </tr>
    <tr class="tr-border-full">

      <td style="min-width:50px"></td>
      <td style="min-width:50px" class="number-align td-border-right">AMOUNT</td>

      <td style="min-width:50px">&nbsp;</td>
      <td style="min-width:50px" class="td-border-right">&nbsp;</td>
      <td style="min-width:50px">&nbsp;</td>
      <td style="min-width:50px">&nbsp;</td>
      <td style="min-width:50px" class="td-border-right">&nbsp;</td>
    </tr>
    <tr>

    </tr>
    <tr>

      <td style="min-width:50px"></td>
      <td style="min-width:50px" class="number-align td-border-right"></td>
    </tr>
    </tbody>
    </table>

＆＃13;

＆＃13;

＆＃13;

这是我的草稿代码，我不确定我是否走上了正确的道路，或者是否有更简单的方法，

$.each("table > tbody > tr:nth-child(3)", function(){
    var $elem = $(this);
    if($elem.text() == " - "){
       $elem.prev().text("");
       $elem.text("");
    }
})

$.each("table > tbody > tr:nth-child(6)", function(){
    var $elem = $(this);
    if($elem.text() == " - "){
       $elem.prev().text("");
       $elem.text("");
    }
})

$.each("table > tbody > tr:nth-child(9)", function(){
    var $elem = $(this);
    if($elem.text() == " - "){
       $elem.prev().text("");
       $elem.text("");
    }
})

删除＆＃34; - ＆＃34;的值后列，我必须排列行，并填补空白，

还有其他方法可以简化它，

谢谢你，

您可以尝试类似

的内容

$(document).ready(function () {

    $("#tblPayslipApproval tr").find("td:contains('-')").each(function(k,v){
        $(v).prev().prev().html("");
        $(v).html("");
    });


});
