优化循环/嵌套循环

Question

我正在循环中工作，自然而然地从一个具有挑战性的开始！我有一个包含多张工作表的工作簿。每个工作表都有完成“小部件”的操作。我正在尝试遍历一系列单元格并按日期搜索以找到匹配的日期。如果该日期匹配，我想在该列的第 7 行添加标准时间。我能够通过强力代码完成这项工作，并为每一列复制并粘贴我的循环。我真的不想对每个选项卡上的所有列都这样做。

我确信有一种方法可以使用我的最后一行和最后一列的计数器来执行嵌套循环，所以一旦我完成了一列中的循环，它就会移动到下一列。我只是不确定如何到达那里。希望对此有所帮助！谢谢！

编辑：基本上我想要做的是从 I12 开始，循环到列底部以查找日期，然后计算我看到的次数以将 PPC 小时数 (I7) 相加。然后，移动到 J12，循环到列底部，移动到 K12，循环到底部，为 Assy 添加小时数。等等……

Answer 1

所以你可以建立你的范围：

Range(A1:D1) -> Range(Cells(A1), Cells(D1)) -> 

Range(Cells(row number, column number), Cells(row number, column number)) -> 

Range(Cells(1, 1), Cells(1, 4))

如果范围是“A1”。我们可以写Range(Cells(1, 1), Cells(1, 1)) 或使用单元格引用Cells(1,1)。

要使用循环构建范围，您可以将一些数字替换为代表循环值的字母，即列/行号。

没有测试，但我想你会明白逻辑：

            ElseIf Cells(1,i).Value = "Weld" Then

            ElseIf Cells(1,i).Value = "PPC" Then
                PPC = PPC + Cells(7,i).Value
            ElseIf Cells(1,i).Value = "QC" Then
                QC = QC + Cells(7,i).Value
