javascript - 如何在选中复选框时获取不同表中的表行数据？

Question

我有一个表，其中给出了一些字段，例如服务、金额、税、操作，当单击复选框时，我希望所有表行数据可以显示在不同的表中，当我选择另一个复选框时，我想要这个行数据也应该添加在它下面的表格中。

$(document).ready(function(){
  $(document).on("change",".tot_amount",function(){  
  if (this.checked){  
     var servicetext = $(this).closest("tr").find('td').eq(0).find('span').text();
     var totalamt = $('#tot_amount').val();
     if(totalamt != ''){
     $('#tot_amount').val(totalamt + ", " + servicetext); 
     }
     else{
     $('#tot_amount').val(servicetext);
     }  
     
      var $tr = $(this).closest("tr");
      $("#table2 tbody").append("<tr class='servicetr'>" + $tr.html() + "</tr>");
  }  
  else{
   var $tr = $(this).closest("tr");  
   $('#table2').find(".servicetr").each(function(){    
     if($tr.html() == $(this).html())
     $(this).remove();  
   });
  
  }
  });
});
