8月19学习练习[两三个TableView并排显示]

要求：在一个view中显示两个tableView，要求左右显示的内容以及行数不一样，且左边每行显示两张图片（分别3个一轮回，2个一轮回）并且显示中国的城市名，右边显示水果名。点击时分别显示城市名或水果名的对话框（偶数的城市不能点击）（所选的图片长短比例不一致）

运行图：

步骤：

1.创建一个tableCell.xib

2.viewController.h:

#import <UIKit/UIKit.h>
@interface DXWViewController : UIViewController<UITableViewDataSource,UITableViewDelegate>
@property (retain, nonatomic) IBOutlet UITableViewCell *ccell;
@end

//
//  DXWViewController.m
//  两个tableView
