Transform data in Power Query

    fx = (tbl)=> Table.ToRows(tbl[[Month],[Week]]){0}&tbl[Value],
    result = Table.FromRows(List.Transform(Table.Split(Source, 3), fx), List.Skip(Table.ColumnNames(Source))&{"Product", "Owner", "Size"})
in
    result

My solution is to split the table every three rows, and then transform each table element in the list.

"Table.ToRows(tbl[[Month],[Week]]){0}&tbl[Value]" This expression converts the first row of the Month and Week columns of each split table into a list, and then merges it with the Value list of the split table.
