可以解决一种一组,一种多组,多种多组,多种一组的tableView

public enum  LSTableViewCellType{    case oneType_oneGroup            //一种  一组    WPBaseCell.Self                           [data]    case oneType_multipleGroup       //一种  多组    [WPBaseCell.Self]                         [data]   //  [[data1,data2],[data1,data2]]    case multipleType_oneGroup       //多种  一组    [WPBaseCell.Self,WPBaseCell2.Self]        [data1,data2]   cell.cout = data.cout    case multipleType_multipleGroup  //多种  多组    [[WPBaseCell1.Self,WPBaseCell2.Self],[]]  [[data1,data2],[data1,data2]]}extension UIViewController{    public  func cellBlock(_ cell:UITableViewCell,data:AnyObject,index:NSInteger)    {        }}extension UITableViewCell{    /**          Cell刷新数据     - parameter data: 数据源     */    public func cellRefreshData(_ data:(AnyObject!))    {        }        /**     计算Cell的高度     - parameter data: 数据源     - returns: 高度     */    public  class func heightForCell(_ data:(AnyObject!)) -> CGFloat    {        return 44;    }  }class LSTableViewDataKit: NSObject,UITableViewDataSource {    var tableView:UITableView!    var data:Array<AnyObject>!    var cellIDs:AnyObject!    var cellType:LSTableViewCellType = .oneType_oneGroup        weak var viewController:UIViewController!    /**     初始化          - parameter data:      数据源     一组  多组     - parameter cellID:    cellID    一种  多种(一组多种,多组多种)     - parameter tableView: tableView          - returns:     */    init(data:Array<AnyObject> = [AnyObject](),cellID:AnyObject,tableView:UITableView = UITableView(frame: CGRect(x: 0, y: 0, width: ScreenWidth, height: ScreenHeight), style: .grouped),viewController:UIViewController) {       super.init()       self.data = data       self.tableView = tableView       self.cellIDs = cellID       self.viewController = viewController       self.tableView.backgroundColor = COLOR_BG       //注册Cell       self.registerCell()       tableView.dataSource = self    }           func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {        //分组        switch self.cellType {        case .oneType_oneGroup:            return  self.data.count        case .oneType_multipleGroup:            if let item = self.data[section] as?
