DAX create empty table with specific column names and no rows

Question

How to create a table with a specified column name and no rows at all. The following oneliner does what I want but shows error message that there should be second argument i

Answer 1

I would like to add to mxix answer a few useful oneliners for making one-column empty table with desired name:

OneLiner1 = TOPN(0, ROW("Product", "Apple"))
OneLiner2 = FILTER(ROW("Product", "Apple"), 1=2)

Or if you want to define column type:

OneLiner3 = TOPN(0, DATATABLE("Product", STRING,{{"Apple"}}) )

So the snipped for bridge table is:

Product_bridge = DISTINCT(
    UNION(
         TOPN(0, ROW("Product", "Apple"))
        ,DISTINCT(      Sales[Prod_Name]        ) 
        ,DISTINCT( Dictionary[Prod_DifferntName])
        ,DISTINCT(  PriceList[P]                )
        ))
