我有一个包含 3 列的表(在 MySQL 中):
Location Category Supplier
A Computers Company X
A Printers Company Y
B Computers Company X
B Printers Company Y
B Software Company Y
C Computers Company Y
C Software Company Z
现在我需要制作一个包含上述信息的矩阵,如下所示:
Computers Printers Software
A Company X Company Y
B Company X Company Y Company Y
C Company Y Company Z
最终我需要在 Excel 中有这个。
实际上,我有可变数量的类别,因此在 MySQL 中为每列连接并不是一个好的选择。我可以用 PHP 编写一个函数,但我想知道是否有更优雅的解决方案。
我在 Excel 中查看了数据透视表,但它们似乎更适合将数字作为值。但也许我忽略了一些东西,因为我自己从不使用 Excel。
有任何想法吗?
最佳答案
我在使用数据透视表时遇到了同样的问题……非常适合摘要,但不适用于文本矩阵。
我刚刚“解除”了一些我使用的代码示例。在这里,我在 A-D 列中有数据,并在 F 列周围构建矩阵(在同一张表中)。
检查这是否有帮助。
我仍然无法让代码看起来正确,所以请注意很多代码在代码窗口之前开始。
代码示例 1:
'Fill in the values
Sheets("TempFile").Select
ListRow = 1
MisMatchCounter = 0
Do Until Cells(ListRow, 1).Value = ""
' Get table entry from third column of list.
TableEntry = Cells(ListRow, 3).Value
On Error Resume Next
If Err.Number > 0 Then MsgBox Err.Number
' Get position of product name within range of row titles.
If TableEntry <> "" Then
TableRow = Application.Match(Cells(ListRow, 1), Range("F3:" & MYLastRowAddress), 0) ' 2 rows less than reality
' Get position of product size within range of column titles.
TableColumn = Application.Match(Cells(ListRow, 2), Range("G2:" & MYLastColAddress), 0)
Set CellToFill = Range("F2").Offset(TableRow, TableColumn)
' If there's already an entry in the cell, separate it from the new entry with a comma and space.
If Err.Number = 0 Then
If CellToFill.Value <> "" Then
CellToFill.Value = CellToFill.Value & ","
CellToFill.Value = CellToFill.Value & TableEntry
Else
CellToFill.Value = TableEntry
End If
Else
MisMatchCounter = MisMatchCounter + 1
Sheets("Errors").Cells(MisMatchCounter, 1).Value = ListRow
Sheets("Errors").Cells(MisMatchCounter, 2).Value = Cells(ListRow, 1)
Sheets("Errors").Cells(MisMatchCounter, 3).Value = Cells(ListRow, 2)
Sheets("Errors").Cells(MisMatchCounter, 4).Value = Cells(ListRow, 3)
Sheets("Errors").Cells(MisMatchCounter, 5).Value = Cells(ListRow, 4)
End If
End If
On Error GoTo 0
ListRow = ListRow + 1
Loop
代码示例 2:
Sub CreateManualMatrix()
Dim TableRow, TableColumn As Integer
Dim TableEntry As String
Dim CellToFill As Range
'Sheet is called Lijst
'Column A is names for top row
'Column B is names for left column
'Column C is value for Matrix
'Matrix Top Row starts at H1
'Matrix Left Column starts at G2
MatrixLastColAddress = Range("H1").End(xlToRight).Address
MatrixLastRow = Range("G65536").End(xlUp).Row
LijstReadColumn = 3
LijstCurrentRow = 2 'make 1 if no header is used
Do Until Sheets("Lijst").Cells(LijstCurrentRow, 1).Value = ""
' Get table entry from third column of list.
TableEntry = Sheets("Lijst").Cells(LijstCurrentRow, LijstReadColumn).Value
' Get position of Employee name within Matrix.
TableColumn = Application.Match(Sheets("Lijst").Cells(LijstCurrentRow, 1), Range("H1:" & MatrixLastColAddress), 0)
' Get position of Qualification Name within Matrix titles.
TableRow = Application.Match(Sheets("Lijst").Cells(LijstCurrentRow, 2), Range("G2:G" & MatrixLastRow), 0)
Set CellToFill = Range("G1").Offset(TableRow, TableColumn)
' If there's already an entry in the cell, separate it from the new entry with a comma and space.
If CellToFill.Value <> "" Then CellToFill.Value = CellToFill.Value & ","
' Add the new entry to the cell.
CellToFill.Value = CellToFill.Value & TableEntry
LijstCurrentRow = LijstCurrentRow + 1
Loop
End Sub
