Reduce table in table to columns

Hello Anonymous 

check out this dynamically solution. It chooses the first column of your single tables that contains the name "value" and uses it's data for the column. Be aware that the source step it's just here to reproduce your scenario. The transformation you can see in the step "CreateListOfValueColumns "

let
    Source = #table
    (
        type table [Column1=table, 204 = table],
        {
            {
                #table  
                (
                    type table [Column1.ColumnName= text, Column1.Value= any ],
                    {
                        {
                            "name1", "value1"
                        },
                        {
                            "name2", "value2"
                        },
                        {
                            "name3", "value3"
                        }
                    }
                ),
                #table  
                (
                    type table [Column1.ColumnName= text, Column1.Value= any ],
                    {
                        {
                            "name1", "abc"
                        },
                        {
                            "name2", "abcddd"
                        }
                    }
                )
            }
        }
    ),
    CreateListOfValueColumns = Table.TransformRows
    (
        Source,
        (rec)=> Table.TransformColumns
        (
            Record.ToTable(rec),
            {
                {
                    "Value",
                    (tbl)=> Table.Column(tbl,List.Select(Table.ColumnNames(tbl), each Text.Contains(Text.Upper(_), "VALUE")){0})
                }
            }
        )[Value]
    ){0},

    CreateFinalTable = Table.FromColumns(CreateListOfValueColumns,Table.ColumnNames(Source))
in
    CreateFinalTable

Copy paste this code to the advanced editor in a new blank query to see how the solution works. If you need to implement it in your data source let me know
