How to select certain cells from koGrid row?

I have a koGrid and I want to select only somes cells (2 cells) from the row. If use canSelectRows: true property I can select the entire row - I don't need this. How to select certain cells from koGrid row ? How to use a rowTemplate in this case?
grid source:

this.gridOptions = {
data: self.people,
enablePaging: true,
pagingOptions: self.pagingOptions,
useExternalSorting: true,
sortInfo: self.sortingOptions,
enableColumnResize: false,
keepLastSelected: false,
multiSelect: true,
showColumnMenu: false,
showFilter: false,
canSelectRows: false,
columnDefs: [{
field: "Age",
displayName: "Age",
width: "33.3%",
sortable: true
},
{
field: "Address",
displayName: "Address",
width: "33%",
sortable: true
},
{
field: "Website",
displayName: "Website",
cellTemplate:
'

',
width: "33%"
}],
selectedItems: self.selectedItems,
plugins: [new koGridSetDefaultSortingPlugin(this.sortingOptions), new koGridSetNextPagePlugin()]

```
};
```

Start with the koGrid selection options in the issue, especially canSelectRows, selectedItems, columnDefs, cellTemplate, and rowTemplate. Determine whether selection can target individual cells rather than rows, then document the supported configuration or define the needed behavior; the issue names no tests or source files to run.
