这个图，对应数据库的的表enegy.
用能种类 用能量，产能量 等等分别对应字段；电力，煤炭，原油这些都是能源种类这个字段的值得
如果我按常规的来写，那么我就要写8条insert语句，我是这样写的。发现后面不好判断而且不好控制。有没有简单点的办法，处理。顺便说下，这只是我做的网页的一小部分，要插几百次，，

提交时．．循环取就行了
因为你的行数是对应的用能种类，如第一行是电力，第二行是煤炭，原油．只是你后面的值变了
所以SQL 基本上只有类型会变
示列如
表结构
foreach (GridViewRow dr in gv.Rows)
{
//根据dr.RowIndex判断是哪个种类
//获取SQL－－insert into enegy(种类，用能量，产能量,运输量) value(固定的种类ID,dr.Cells[1].Text,dr.Cells[2].Text,dr.Cells[3].Text)
}
这就生成了．你需要的SQL．然后进行数据库操作
我拖gridview 他不显示的。。
