How to set one title of the table in the mid?

My code :

               html.Div(
        dash_table.DataTable(
            id='review_table',
            columns=[{"name": i, "id": i} for i in ['Date', 'Client Username', 'Review']],
            style_cell_conditional=[
                {'if': {'column_id': 'Client Username'},
                 'width': '17%'},
                {'if': {'column_id': 'Review'},
                 'textAlign': 'center',

                 },
            ],

            style_cell={
                'color': 'Black',
                'textAlign': 'center',
                'font_size': '16px',
                'backgroundColor': '#bfbfbf',
                'whiteSpace': 'normal',
            }, style_header={
                'font_size': '20px',
                'maxWidth': '0',
                'fontWeight': 'bold',
            },
            tooltip_data=[],

            tooltip_duration=None,
            sort_action='native',
            data=[],
        ),
        className="twelve columns Table1",
    )

Hi @EddyJARJOURA, and welcome to the Dash community!

Try using style_header_conditional rather than style_cell_conditional
