        valuePrepareFunction: (cell, row) => {
          console.log(row.bindedSn);
          this.bnsn = row.bindedSn;
          return row.bindedSn;
          // console.log(row);
        },
      },
      bindedTime: {
        title: "bindedTime",
        type: "string",
      },
      longitude: {
        title: "longitude",
        type: "string",
      },
      latitude: {
        title: "latitude",
        type: "string",
      },
      localisation: {
        title: "localisation",

      },
      openModal: {
        title: "openModal",
        type: "custom",
        renderComponent: NbListComponent,
      },
    },
  };

as shown at last column there is a button that open a modal , by clicking on the button I want to pass bindedSn data of it's row .
