excel表格的列数，最大是256列，超过是不行的。
要用vba处理，大致代码如下，没看懂你到底要实现什么，细节自己调整
Dim App As New MSExcel.Application
Dim Wb As MSExcel.Workbook = App.WorkBooks.Add
Dim ws = Wb.WorkSheets(1)
ws.name = "test"
Dim dict As new Dictionary(of String,Integer)

Dim zimu As String = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
Dim i As Integer = 0
Dim idx As Integer
Dim Formula As String = "="
Dim k As Integer
Dim km As Integer
For i = 0 To lst.Count - 1
idx = i*7+1
k = Math.Floor((idx+2) / 26) - 1
km = (idx+2) Mod 26
'Output.Show("k=" & k & ", km=" & km)
If k< 0 Then
Formula &= zimu(km) & "{0}+"
Else
Formula &= zimu(k) & zimu(km) & "{0}+"
End If
k = Math.Floor((idx+3) / 26) - 1
km = (idx+3) Mod 26
If k< 0 Then
Formula &= zimu(km) & "{0}+"
Else
