我的桌子看起来像这样。现在我需要在每周行之后显示总测试和周期运行的总周数。有什么帮助吗？
目前表格如下：
<!DOCTYPE html>

<style>
.header-fixed {

thead {

}
</style>
</head>

预期表应该是：
Week Project OS TotalTests #cycle of run
1 P1 Windows 0 0
P2 Linux,UFO 4799 1
2 P3 Windows 234 5
以下是代码：
Week Project OS TotalTests #cycle of run
1 P1 Windows 0 1
P2 Linux,UFO 4799 1
Total: 4799 2
2 P3 Windows 234 5
Total: 234 5

在这种情况下，在循环中向后移动会使后来找到放置每个总行的位置变得更加复杂。在这里你有我的方法...

一条建议，处理和修改jQuery对象和DOM元素比javascript数组或字符串慢，所以考虑将它用于循环并最小化DOM操作。例如，而不是......
for (...) {
let $tr = $('<tr/>');
$tr.append("<td>" + data[i].Project + "</td>");
$tr.append("<td>" + data[i].OS + "</td>");
.....
$('#GraphTable').prepend($tr);
}
...使用......
let rows = [];
for (...) {
let row = '<tr>' +;
'<td>' + data[i].Project + '</td>' +
'<td>' + data[i].OS + '</td>';
.....
'</tr>';
rows.push(row);
}
$('#GraphTable').prepend(rows.join(''));
根据循环的大小，它可以更快。
当你需要求和时，记得把你的字符串转换成数字......
Total = Total + parseInt(data[i].CycleRun);
我希望它有所帮助
