How to create a slicer based on column headers

[RenateBK]

Hello, 

I am trying to set up a slicer for a data set where all the data is categoried strictly through column headers.

Received         Opened            Click

10                   6                        2

12                   9                        3

etc.

I would like to create a slicer based on column names, but due to how the data is set up I cannot drag and drop, as my slicer turns out like this:

From reading other threads I have created a separate table and I've managed to create a list of the headers. However, I am struggling with how to establish a relationship between this table and the column headers and cannot make that function 

let
    Source = Table.ColumnNames(TheTable as table) as list,
    #"Converted to Table" = Table.FromList(Source, null, {"TheHeaders"})
in
    #"Converted to Table"

How can I set it up using the list or is there a better/easier way to set this up?

Thank you

Thank you so much for some great sources, I managed to solve my issue using field parameters.

@RenateBK , the expected output is not clear. But I think field parameters can help
