cant add button widget into column component

{ a!columnsLayout( columns: { a!columnLayout( contents: { a!buttonArrayLayout( buttons: { a!buttonWidget( label: "Button", style: "NORMAL" ) }, align: "START" ) } ), a!columnLayout( contents: {} ), a!columnLayout( contents: {} ) } ) }

To use a button widget, we have to use either a button layout or a button array layout. Further, if you want to use a button inside a column, you can use the code attached below.

{
  a!columnsLayout(
    columns: {
      a!columnLayout(
        contents: {
          a!buttonArrayLayout(
            buttons: {
              a!buttonWidget(
                label: "Button",
                style: "NORMAL"
              )
            },
            align: "START"
          )
          
        }
      ),
      a!columnLayout(
        contents: {}
      )
    }
  )
}

Please clarify if it is a column layout or a grid column. But in either of the cases, you can! If you face a problem, please attach the code. 

 a!columnLayout(
   contents: {
     a!buttonArrayLayout(
       buttons: {
         a!buttonWidget(label: "Button Label")
       }
     )
   }
 )

You can, but have to use the right level of nesting and using the correct syntax as suggested by other members.
