--------------------------
 b        c          d
 e        f           g
 h        i            j

Schema is —>

grouping grp_3 {
        leaf B {
            type string;
        }
        leaf C {
            type string;
        }
        leaf D {
            type string;
        }
     }
grouping grp_2 {
        container con_3 {
            config false;
            list con_3 {
                key B;
                ordered-by user;
                uses grp_3;
            }
        }
    }
grouping grp_1 {
        container con_1 {
            container con_2 {
                config false;
                uses grp_2;
            }
        }
    }
    augment "system" {
        uses grp_1;
    }

=============================================

Question is → I need to add another column at the the first named “A” and is having a static value i.e fixed value. how do i modify the existing code for getting desired results?

A       B        C         D                         
--------------------------------
a       b        c         d
         e        f          g
         h        i           j

Hello @Harshitha,

Is it config false data? Can you use show templates?

See ConfD user guide 20.29.2. Show templates, example examples.confd/cli/show_templates and
tailf:cli-show-template annotation (and type cli-template-string). The annotation and type is described in the tailf_yang_cli_extensions section.
