Calculate row step like Excel

try this:

// output
let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    acc = List.Accumulate(
               Source[Column1], 
               {null, {}}, 
               (s,c)=>let n=s{0}??List.Sum(Source[Column1]) 
                      in {n*2.32+c-n, s{1}&{{c, n, n*2.32, n*2.32+c, n*2.32+c-n}}}
          ),
    result = Table.TransformColumns(#table(null, acc{1}), {}, each Number.Round(_, 2))
in
    result
