今天做了一个简例，用tableView实现excel冻结窗格功能 Demo：https://git.oschina.net/sunflowrs/FreezePanes.git
初始化Tableview 实现代理
|
1
|
class BasicTableView:UITableView,UITableViewDelegate,UITableViewDataSource
|
声明变量时，数组和字典，最好设置成已知类型，避免惹麻烦
|
1
2
|
var titleArr:Array<String> = []
var listArr:Array<Dictionary<String,String>> = []
|
改写父类方法时要用override关键字

override func awakeFromNib() {
super.awakeFromNib()
self.delegate = self
self.dataSource = self
self.separatorStyle = UITableViewCellSeparatorStyle.none
self.showsVerticalScrollIndicator = false
}

需要注意：避免爆红 ， 一定要实现一下两种方法
