Datatable sub data

Is it possible to define a column like below in datatable?

{ id: "tax['tax1']", header: "Tax 1", template: "#tax.tax1#%", editor: "text", }, { id: "tax['tax2']", header: "Tax 2", template: "#tax.tax2#%", editor: "text", }

{
    id: "tax1",
    header: "Tax 1",
    map: "#tax.tax1#%",
    editor: "text",
},
{
    id: "tax2",
    header: "Tax 2",
    map: "#tax.tax2#%",
    editor: "text",
}

thank you
