如何追加行,然后动态更改第二行的行跨度。我想发生的事情是这样的:
<table border='1'>
<tbody>
<tr>
<td rowspan="2">1</td>
<td>2</td>
</tr>
<tr>
<td>2</td>
</tr>
<tr>
<td rowspan="2">1</td>
<td>2</td>
</tr>
<tr>
<td>2</td>
</tr>
<tr>
<td rowspan="2">1</td>
<td>2</td>
</tr>
<tr>
<td>2</td>
</tr>
<tr>
<td rowspan="2">1</td>
<td>2</td>
</tr>
<tr>
<td>2</td>
</tr>
<tr>
<td rowspan="2">1</td>
<td>2</td>
</tr>
<tr>
<td>2</td>
</tr>
</tbody>
</table>
感谢您的帮助。
FYI
:我要发生的事情是先附加,然后在附加行后更改行跨度

希望我能达到您的要求。
我根据第二个片段的结果。
for (var i = 0; i < 10; i++) {
var tr = $("<tr></tr>")
tr.append("<td>1</td>");
tr.append("<td>2</td>");
$("table tbody").append(tr)
}
$('button').click(function(){
$('table tr:odd td:first-child').remove();
$('table tr:even td:first-child').attr('rowspan', 2);
});

只需添加mod (%)
for (var i = 0; i < 10; i++) {
var tr = $("<tr></tr>");
if(i%2===0){
tr.append("<td rowspan='2'>1</td>");
}
tr.append("<td>2</td>");
$("table tbody").append(tr)
}
td, th {
border: 1px solid #ddd;
padding: 8px;
}

尝试使用html字符串,然后将其附加到您的元素上,并使行跨度动态化,例如:
var html_string = '<tr>'
for (var i = 0; i < 10; i++) {
html_string+= '<td rowspan="'+i+'">1</td>'
html_string += '<td>2</td>'
}
html_string +='</tr>'
$("table tbody").append(html_string)

下面的代码可能有帮助,
for (var i = 0; i < 10; i++) {
var tr = $("<tr></tr>");
tr.append("<td>1</td>");
tr.append("<td>2</td>");
$("table tbody").append(tr)
}
$('table tr:odd td:first-child').remove();
$('table tr:even td:first-child').attr('rowspan', 2);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table border='1'>
<tbody></tbody>
