Selecting first and last column only

I have a table from excel spreadsheet and I'm trying to keep only the first and last columns, as I will be adding to it monthly. I've tried the information from this post but I cannot seem to make it work. Below is the query currently before I'm ready to select those columns. Suggestions are helpful.

 

 

 

let
    Source = Excel.Workbook(File.Contents("\\xxxx\DoIT\SpiUsers1\KENT.LUTTRELL\Personal Items\Project Files\IES Docs\IES DB Data\IES Table Growth.xlsx"), null, true),
    #"Table Growth_Sheet" = Source{[Item="Table Growth",Kind="Sheet"]}[Data],
    #"Removed Blank Rows" = Table.SelectRows(#"Table Growth_Sheet", each not List.IsEmpty(List.RemoveMatchingItems(Record.FieldValues(_), {"", null}))),
    #"Removed Bottom Rows" = Table.RemoveLastN(#"Removed Blank Rows",5),
    #"Removed Columns" = Table.RemoveColumns(#"Removed Bottom Rows",{"Column7", "Column8"}),
    #"Transposed Table" = Table.Transpose(#"Removed Columns")
in
    #"Transposed Table"

Re: Selecting first and last column only

Hi

You'd have to add the following step:

 

let
    Source = Excel.Workbook(File.Contents("\\xxxx\DoIT\SpiUsers1\KENT.LUTTRELL\Personal Items\Project Files\IES Docs\IES DB Data\IES Table Growth.xlsx"), null, true),
    #"Table Growth_Sheet" = Source{[Item="Table Growth",Kind="Sheet"]}[Data],
    #"Removed Blank Rows" = Table.SelectRows(#"Table Growth_Sheet", each not List.IsEmpty(List.RemoveMatchingItems(Record.FieldValues(_), {"", null}))),
    #"Removed Bottom Rows" = Table.RemoveLastN(#"Removed Blank Rows",5),
    #"Removed Columns" = Table.RemoveColumns(#"Removed Bottom Rows",{"Column7", "Column8"}),
    #"Transposed Table" = Table.Transpose(#"Removed Columns"),
    KeepFirstAndLastColumn = 
        Table.SelectColumns(
           #"Transposed Table",
           { List.First ( Table.ColumnNames ( #"Transposed Table" ) ),
             List.Last ( Table.ColumnNames ( #"Transposed Table" ) ) } 
          )
in
    KeepFirstAndLastColumn
