e917. Setting the Width of a Column in a JTable Component

By default, the column widths of all columns are equal. In order for column width adjustments to be made, autoResizeMode must be disabled.
    int rows = 3;
    int cols = 3;
    JTable table = new JTable(rows, cols);
    
    // Disable auto resizing
    table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
    
    // Set the first visible column to 100 pixels wide
    int vColIndex = 0;
    TableColumn col = table.getColumnModel().getColumn(vColIndex);
    int width = 100;
    col.setPreferredWidth(width);
