        { select: 1, sort: "asc" },

        // Append a button to the seventh column
        {
            select: 6,
            render: function(data, cell, row) {
                return data + "<button type='button' data-row='"  + row.dataIndex + "'>Select</button>";
            }
        }
    ]
});

You can use the same properties in your markup. Just add the property to the th element as a data-{property} attribute:

<table>
    <thead>
        <th data-sortable="false">Heading 1</th>
        <th data-type="date" data-format="MMM DD, YYYY">Heading 2</th>
        <th data-hidden="true">Heading 3</th>
        ...
    </thead>
    ...
</table>
