这篇文章很有帮助，它和其他答案差不多，但是总结和简洁

其中，他只将它们应用于左侧和右侧，但UIEdgeInsetsMake初始化允许为所有四个点添加填充。

func UIEdgeInsetsMake(_ top: CGFloat, _ left: CGFloat, _ bottom: CGFloat, _ right: CGFloat) -> UIEdgeInsets Description Creates an edge inset for a button or view. An inset is a margin around a rectangle. Positive values represent margins closer to the center of the rectangle, while negative values represent margins further from the center. Parameters top: The inset at the top of an object. left: The inset on the left of an object bottom: The inset on the bottom of an object. right: The inset on the right of an object. Returns An inset for a button or view

注意，UIEdgeInsets也可以用来实现同样的效果。

Xcode 9.3/Swift 4

例子在swift 3..

Crease a single view application add tableview in view controller add a customcell for tablview cell view controller code is bellow like class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource { @IBOutlet weak var tableView: UITableView! var arraytable = [[String:Any]]() override func viewDidLoad() { super.viewDidLoad() arraytable = [ ["title":"About Us","detail":"RA-InfoTech Ltd -A Joint Venture IT Company formed by Bank Asia Ltd"], ["title":"Contact","detail":"Bengal Center (4th & 6th Floor), 28, Topkhana Road, Dhaka - 1000, Bangladesh"] ] tableView.delegate = self tableView.dataSource = self //For Auto Resize Table View Cell; tableView.estimatedRowHeight = 44 tableView.rowHeight = UITableViewAutomaticDimension //Detault Background clear tableView.backgroundColor = UIColor.clear } func numberOfSections(in tableView: UITableView) -> Int { return arraytable.count } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return 1 } // Set the spacing between sections func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat { return 10 } // Make the background color show through func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? { let headerView = UIView() headerView.backgroundColor = UIColor.clear return headerView } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "cell")! as! CustomCell cell.tv_title.text = arraytable[indexPath.section]["title"] as! String? cell.tv_details.text = arraytable[indexPath.section]["detail"] as! String? //label height dynamically increase cell.tv_details.numberOfLines = 0 //For bottom border to tv_title; let frame = cell.tv_title.frame let bottomLayer = CALayer() bottomLayer.frame = CGRect(x: 0, y: frame.height - 1, width: frame.width, height: 1) bottomLayer.backgroundColor = UIColor.black.cgColor cell.tv_title.layer.addSublayer(bottomLayer) //borderColor,borderWidth, cornerRadius cell.backgroundColor = UIColor.lightGray cell.layer.borderColor = UIColor.red.cgColor cell.layer.borderWidth = 1 cell.layer.cornerRadius = 8 cell.clipsToBounds = true return cell } } Download full source to Github : link https://github.com/enamul95/CustomSectionTable

使用节而不是行 每个section应该返回一行 使用indexPath分配单元格数据。Section，而不是row 实现UITableView委托方法hightforheader并返回你想要的间距

如果你不想使用任何标题，使用标题作为间距也可以。否则，这可能不是最好的主意。我在想的是创建一个自定义单元格视图。

例子:

用笔尖 在代码中

在自定义单元格中，创建一个带有约束的背景视图，这样它就不会填充整个单元格，给它一些填充。

然后，使tableview背景不可见，并删除分隔符:

// Make the background invisible
tableView.backgroundView = UIView()
tableView.backgroundColor = .clear

// Remove the separators
tableview.separatorStyle = .none

我在Swift 4中是这样解决的。

我创建了UITableViewCell的扩展，并包括以下代码:

override open var frame: CGRect {
    get {
        return super.frame
    }
    set (newFrame) {
        var frame =  newFrame
        frame.origin.y += 10
        frame.origin.x += 10
        frame.size.height -= 15
        frame.size.width -= 2 * 10
        super.frame = frame
    }
}

override open func awakeFromNib() {
    super.awakeFromNib()
    layer.cornerRadius = 15
    layer.masksToBounds = false
}

我希望这对你有所帮助。
