RE: Display UI

You can restructure the list in a dictionary format using different CDTs and make the grid run on a local variable.

Can I get reference code Please?

Here I have used two different record having some relation between them. I believe in your case also the tables must have some relation with each others.
You can have a rough idea from here, if that helps you.

a!localVariables(
local!tickets: rule!PM_QR(
recordType: 'recordType!{5f0bd786-7684-4f3e-aff0-378836d403d9}PM Tickets',

Hi Rishikesh Raj, I have some relation between two tables(Id from one table and sourceId from other table), Using I need to show download Icon for 2 columns. 

* For the first 2 columns, I will be showing the data by querying from another table. Help me on this code.

Thanks in advance.Please suggest on priority

a!localVariables(
  local!crAppCollateral_cdt: rule!CR_APP_QE_getAppCollateralForDocGeneration(
    cif_int: ri!cif_int,
    collateralFlag_int: 0,
    requestId_int: ri!requestId_int
  ),
  local!crCustDoc_cdt: rule!CR_CUST_QE_getCustomerDocDataBasedOnFilters(
    cif_int: ri!cif_int,
    requestId_int: ri!requestId_int,
    sourceRowId_int: index(local!crAppCollateral_cdt, "id_int", "")
  ),
  a!gridField(
    labelPosition: "ABOVE",
    data: local!crAppCollateral_cdt,
    columns: {
      a!gridColumn(
        label: " Type",
        value: index(
          fv!row,
          "collateralDescription_txt"
        )
      ),
      a!gridColumn(
        label: " Type Detail",
        value: index(
          fv!row,
          "collateralTypeDescription_txt"
        )
      ),
      a!gridColumn(
        label: "Conventional",
       ###here I need to show download icon###
      ),
      a!gridColumn(
        label: "Non Conventional",
        ###download icon here as well###
        
      )
    }
  )
)

Tell me the exact purpose of using icon in these two columns. what will be the work of download icon here.

Or you just need to show download icon. 

Its to download the documents, which is available for the type of tracker.

Is Document Id  available in crCustDoc_cdt ?

yes it is available in the table.
