PML Value list in grid,PML Value list in grid

can anyone help me how to use createValueList(String,!array)  method in grid and how does it work?
lets suppose i have a 4 pipe names in array i need to have that 4 pipes in a single cell of a grid like a list to view that 4 pipes

Hello ASEEM,

Here is an example:

   !listValues = ARRAY()
   !listValues.append('Value 1')
   !listValues.append('Value 2')
   
   !this.grid.createValueList('MyValueList', !listValues)
   
   !this.grid.assignValueListToColumn('MyValueList', 2)

Where 2 in my case is the column number on which the list will be applied.
