 //先设置背景色

    _backImgView = [[UIImageView alloc]initWithFrame:CGRectMake(20 * KSCALE_X, 0, IPHONE_WIDTH - 40 * KSCALE_X, self.frame.size.height)];

    _backImgView.backgroundColor = kColor(231, 231, 231);

    [self.contentView addSubview:_backImgView];

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
