title: DAX create empty table with specific column names and no rows
body: <p>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 in ROW function. </p>
  
  <pre><code>EmptyTable = ROW ("Product")
  </code></pre>
  
  <p>I would like to use it for making bridge tables with desired column name. For example I want Product_bridge table to have a column "Product".</p>
  
  <pre><code>Product_bridge = DISTINCT(
      UNION(
           DISTINCT(      Sales[Prod_Name]        ) 
          ,DISTINCT( Dictionary[Prod_DifferntName])
          ,DISTINCT(  PriceList[P]                )
          ))
  </code></pre>
  
  <p>The code above gets me the name of the first table, in this case Prod_Name. </p>
