－、建立 UITableView
    
     DataTable = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 420)];
     [DataTable setDelegate:self];
     [DataTable setDataSource:self];
     [self.view addSubview:DataTable];
     [DataTable release];
    
    
    二、UITableView各Method说
    
    
    //Section总数
    - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView{
     return TitleData;
    }
    
    
    // Section Titles
    //每个section显示的标题
    - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
     return @"";
    }
    
    
    //指定有多少个分区(Section)，默认为1
    - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
     return 4;
    }
    
    
    //指定每个分区中有多少行，默认为1
    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    }
    
    
    //绘制Cell
    -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";
      
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:
                                 SimpleTableIdentifier];
     
       if (cell == nil) {  
            cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
                                           reuseIdentifier: SimpleTableIdentifier] autorelease];
    
     }
     cell.imageView.image=image;//未选cell时的图片
     cell.imageView.highlightedImage=highlightImage;//选中cell后的图片
     cell.text=//.....
     return cell;
    }
    
    
    //行缩进
    -(NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath{
     NSUInteger row = [indexPath row];
     return row;
    }
    
    
    //改变行的高度
    - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
        return 40;
    }
    
    
    //定位
    [TopicsTable setContentOffset:CGPointMake(0, promiseNum * 44 + Chapter * 20)];
    
    
    //返回当前所选cell
    NSIndexPath *ip = [NSIndexPath indexPathForRow:row inSection:section];
    [TopicsTable selectRowAtIndexPath:ip animated:YES scrollPosition:UITableViewScrollPositionNone];
    
    
    [tableView setSeparatorStyle:UITableViewCellSelectionStyleNone];
    
    
    //选中Cell响应事件
    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    
     [tableView deselectRowAtIndexPath:indexPath animated:YES];//选中后的反显颜色即刻消失
    }
    
    
    //判断选中的行（阻止选中第一行）
    -(NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
    {
        NSUInteger row = [indexPath row];
        if (row == 0)
            return nil; 
        return indexPath;
    }
    
    
    //划动cell是否出现del按钮
    - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    }
    
    
    //编辑状态
    - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
    forRowAtIndexPath:(NSIndexPath *)indexPath
    {
    
    [topicsTable setContentSize:CGSizeMake(0,controller.promiseNum * 44)];
    //右侧添加一个索引表
    - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView{
    } 
    
    //返回Section标题内容
    - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
    }
    
    //自定义划动时del按钮内容
    - (NSString *)tableView:(UITableView *)tableView
    titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath
    
    
    //跳到指的row or section
    [tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] atScrollPosition:UITableViewScrollPositionBottom animated:NO];
    
    三、在UITableViewCell上建立UILable多行显示
    
    
    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
        static NSString *CellIdentifier = @"Cell";   
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if (cell == nil) {
            cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
      UILabel *Datalabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 0, 320, 44)];
      [Datalabel setTag:100];
      Datalabel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
      [cell.contentView addSubview:Datalabel];
      [Datalabel release];
     } 
     UILabel *Datalabel = (UILabel *)[cell.contentView viewWithTag:100];
     [Datalabel setFont:[UIFont boldSystemFontOfSize:18]];
     Datalabel.text = [data.DataArray objectAtIndex:indexPath.row];
     cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
        return cell;
    }
    
    //选中cell时的颜色
    
    typedef enum {
        UITableViewCellSelectionStyleNone,
        UITableViewCellSelectionStyleBlue,
        UITableViewCellSelectionStyleGray
    } UITableViewCellSelectionStyle
    
    //cell右边按钮格式
    
    typedef enum {
        UITableViewCellAccessoryNone,                   // don't show any accessory view
        UITableViewCellAccessoryDisclosureIndicator,    // regular chevron. doesn't track
        UITableViewCellAccessoryDetailDisclosureButton, // blue button w/ chevron. tracks
        UITableViewCellAccessoryCheckmark               // checkmark. doesn't track
    } UITableViewCellAccessoryType
    
    //是否加换行线
    
    typedef enum {
        UITableViewCellSeparatorStyleNone,
        UITableViewCellSeparatorStyleSingleLine
    } UITableViewCellSeparatorStyle
    
     
    
    //改变换行线颜色lyttzx.com
    
    tableView.separatorColor = [UIColor blueColor];

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
    {
       UITableViewCell *cell = [selftableView:tableView cellForRowAtIndexPath:indexPath];
        return cell.frame.size.height;
    }
    
    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        NSArray* nibView =  [[NSBundle mainBundle] loadNibNamed:@"ManagerTileCell" owner:nil options:nil];
        UITableViewCell *cell = [nibView objectAtIndex:0];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
        ///
    
        UILabel *label = (UILabel*)[cell viewWithTag:0];
        label.text = @"test";
        return cell;
    }
