I am using rowGroup grouped by fiscal year (4 digit string);
When I add a new row via Editor, I am expecting the row to be added to the appropriate group.
What it does do is add a duplicate group and adds the row to the duplicate group at the bottom of the table.

I do not save data back to the server during the add row process. Changes to the table are all saved at once triggered by user action.

Suggestions? Is there a way during the row create process to tell the DataTable to do a full table draw instead of just the row?

(rowGroup is missing from the list of extensions in the Category dropdown for these forums)

 this.editorDef = {
        table: "#" + this.tableId,
        template: "#EquityTemplate",
        display: 'bootstrap',
        fields: [
            {
                name: "FiscalYear", label: "Fiscal Year", type: "display"
            },
            {
                data: "one",
                id:"ddlEditorEquity",
                name: "one",
