您好我有这些代码来删除表行，我的问题是，当我删除数字之间的行时，例如，我有4行，而我删除了＃2行，行的编号将像1,3 ，4 ..但我需要成为1,2,3，我将如何实现这一目标？感谢您的帮助
这是我动态添加表格的方式
var rowCount = $('#mhTable >tbody >tr').length;
var count = rowCount + 1;
var host = window.location.protocol + "//" + window.location.host + "/" + "\files/Icons/delete.png";
$('#mhAddRow').click(function(e)
{
$("#mhTable tr:last").after('<tr id="row' + count + '">'
+ '<td> <sup> <img class="DeleteRow" style="cursor:pointer;" id="rowDelete" name="rowDelete" height="7" width="7" src="'+host+'"> </sup> <input type="text" id="rowsID'+count+'" name="rows['+count+']" style="width:73%;text-align:center;" value="'+count+'" readOnly="readonly"> </input> </td>'
+ '<td> <input type="text" style="width:98%;" id="process" class="process" name="process['+count+']" value=""> </input> </td>'
+ '<td> <input type="text" style="width:96%;" id="PIC" class="PIC" name="PIC['+count+']" value="" > </input> </td> '
+ '<td> <input type="text" style="width:95%;text-align:right;" id="prev" class="prev" name="prev['+count+']" onkeyup="ManhourSaving();totalmhPrevious();ManhourSavingRatio();mhInMinutes();savedMHyearly();costAnnual()" onkeypress="return isNumberKey(event)" maxlength="5" value="" ></input> </td> '

$.post('mis.php/new_development_request/loadView_newDevelopmentRequest', {counter: count});
count++;
});
首先删除该行，然后使用$ .each函数更新其他tr
看一下小提琴以获得您的结果：https : //jsfiddle.net/hL625r4p/
$(document).ready(function () {
$("button").click(function () {
$(this).closest('tr').remove();
$(".row-id").each(function (i){
$(this).text(i+1);
});
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table border='1'>
<tr>
<td class='row-id'>1</td>
<td>Row 1</td>
<td><button>Delete</button></td>
</tr>
<tr>
<td class='row-id'>2</td>
<td>Row 2</td>
<td><button>Delete</button></td>

<tr>
<td class='row-id'>3</td>
