为什么UITableView为空？

我想在UITableView中构建菜单，但是我做错了什么。我做错了什么？我得到空的UITableView。我不知道怎么了 也许有什么主意？
这是我的代码：

.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
{
    IBOutlet UITableView *tblSimpleTable;
    NSMutableArray *array1;
    UIBarButtonItem *addButton;
    BOOL manyCells;
    UIView *headerView;
    UITapGestureRecognizer  *headerTapped;
    NSMutableArray *history;
    NSString *valueToSave;
    NSMutableArray      *sectionTitleArray;
    NSMutableDictionary *sectionContentDict;
    NSMutableArray      *arrayForBool;
    UITableView *table;
}

- (IBAction) EditTable:(id)sender;

@end

.m

#import "ViewController.h"

@interface ViewController ()

@end
