c# - 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数。我已经计算了这些值（ <%= owetotal %> , <%=paidtotal %>, <%= origtotal %>）只需要将它们放置在正确的位置，我似乎无法按照我想要的方式格式化它.

目前它看起来像这样：

我希望它看起来像这样：

Answer 1

您最好在控制器的 Page_Load 处理程序中执行此操作。向每个表添加新行并将您的总计值放在那里。并写下这个：

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
    }
}

Answer 2

在您的 SQL 语句中，添加

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