我有一个表(在MysqL中)有3列：
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中使用它.
实际上我有不同数量的类别,所以在MysqL中使用每列的连接进行操作并不是一个好选择.我可以在PHP中编写一个函数,但我想知道是否有更优雅的解决方案.
我在Excel中查看了一个数据透视表,但它们似乎更适合数字作为值.但也许我忽视了一些事情,因为我自己从不使用Excel.
有任何想法吗？
解决方法
我遇到了与数据透视表相同的问题…完美的摘要,但不适用于文本矩阵.
我刚刚“解除了”我使用过的一些代码示例.这里我有A-D列中的数据,并在F列周围构建矩阵(在同一张纸中).
检查一下这是否有帮助.
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启动.
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,Range("H1:" & MatrixLastColAddress),0)
' Get position of Qualification Name within Matrix titles.
TableRow = Application.Match(Sheets("Lijst").Cells(LijstCurrentRow,Range("G2:G" & MatrixLastRow),0)
Set CellToFill = Range("G1").Offset(TableRow,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
