EXCEL条件格式的使用

，这个怎么通过条件格式实现单元格颜色的变化，应该看的很清楚的吧，如有问题，请跟帖，歇歇。

Function FindStringInFirstColumn(str As String) As Integer
    Dim ws As Worksheet
    Dim lastRow As Integer
    Dim i As Integer
    
    Set ws = ThisWorkbook.Sheets("Sheet1") '修改为你的工作表名称
    
    lastRow = ws.Cells(Rows.Count, 1).End(xlUp).Row
    
    For i = 1 To lastRow
        If ws.Cells(i, 1).Value = str Then
            FindStringInFirstColumn = i
            Exit Function
        End If
    Next i
    
    FindStringInFirstColumn = -1
End Function

Sub 宏1()
'
' 宏1 宏
'

'
    For i = 10 To 20
        For j = 1 To 10
            If FindStringInFirstColumn(Cells(i, j).Value & "") > 0 Then
                Cells(FindStringInFirstColumn(Cells(i, j).Value & ""), j).Select
        
                With Selection.Interior
                    .Pattern = xlSolid
                    .PatternColorIndex = xlAutomatic
                    .Color = 65535
                    .TintAndShade = 0
                    .PatternTintAndShade = 0
                End With
            End If
        Next
    Next
End Sub
