Question

我正在创建一个代码，它将帮助我将一个文件夹中的不同文件合并到一个唯一的电子表格中。（输出应为平面文件，其中包含所有电子表格中的所有信息。）

所有电子表格的列数将相同，但是行数可能会有所不同。也就是说，行数应该是动态的。（不过，以防万一，我想从源代码中对行和列进行二维编码。）

我只能编写一个特定的范围，但是在粘贴时，数据中有几个空白（在新创建的电子表格中复制的每个电子表格之间）。

关于从源代码对所有行和列进行动态编码并将其粘贴到新的电子表格中而没有任何空白行的建议吗？

这是一种可能的解决方案：

Option Explicit

Sub test()

    Dim ws As Worksheet
    Dim LastColumn As Long, LastRow As Long, MaxRow As Long, i As Long
    Dim rng As Range

    For Each ws In ThisWorkbook.Worksheets '<- Loop sheets

        With ws

            MaxRow = 0
            LastColumn = .Cells(1, .Columns.Count).End(xlToLeft).Column '<- Find last column of row 1

            For i = 1 To LastColumn '<- Loop from column 1 to last column

                LastRow = .Cells(.Rows.Count, i).End(xlUp).Row '<- Find last row of column i

                If MaxRow < LastRow Then '<- Check if max row if smallers than last row
                    MaxRow = LastRow '<- if max row is small that last row, max row get the value of last row
                End If

            Next i

            Set rng = .Range(Cells(1, 1), Cells(MaxRow, LastColumn)) '<- Set the range to be copy. range if from A1 to last column last row

        End With

    Next ws

End Sub
