Same sort of defaulting should apply for this method because it's public. `cell` from `this.getCell(cell)`, `model` from `this.getRecord(cell)`, and `col` from ...hmm, there's no `this.getColumn(cell)`. It would be scope-creepy to update DataTable.Core's `getColumn` to relay through the table view to the body (or header?) view to calculate from the cell.  So I guess you could inline hack it with a TODO or FIXME for now.
