editable

Specifies whether the column will be editable.
Defaults to true, meaning editing will be allowed if enabled for the grid.

$("#grid").shieldGrid({
    dataSource: {
        data: [
            { ID: 1, firstName: "name1", middleName: "middleName1", lastName: "lastName1" },
            { ID: 2, firstName: "name2", middleName: "middleName2", lastName: "lastName2"}
        ]
    },
    editing: {
        enabled: true
    },
    columns: [
        { field: "ID", filterable: false },
        { field: "firstName" },
