在每个表的末尾添加总计行

Question

我希望为每个位置添加一行，如下图所示。该行将显示每列的总计。我已经计算了这些值（＆lt;％= owetotal％＆gt;，＆lt;％= paidtotal％＆gt;，＆lt;％= origtotal％＆gt;）只需要将它们放在正确的位置，我似乎无法格式化就像我想要的那样。

目前它看起来像这样：

我希望它看起来像这样：

Answer 1

在SQL语句中，添加

UNION SELECT 'Totals', sum(Owes), sum (Paid), sum(OrigAmt), '' FROM Accounts

Answer 2

您可以在控制器的Page_Load处理程序中执行此操作。向每个表添加新行并将其放在总计值中。写下关于这个问题：

foreach(var column in table.Columns)
{
    foreach(var field in column)
    {
        //check if it isn't last row
        //write the sum of (0..n-1) fields to lsat field in column
    }
}
