在UI布局時，添加一個尺寸不固定的NSTableView：（需放置于NSScrollView實例對象上）

其中NSTableView的代理方法——Delegate和DataSource：

//MARK:NSTableViewDelegate,NSTableViewDataSource
func tableView(_ tableView: NSTableView, heightOfRow row: Int) -> CGFloat {
    return 25.0
}
func numberOfRows(in tableView: NSTableView) -> Int {
    return 36
}
func tableView(_ tableView: NSTableView, objectValueFor tableColumn: NSTableColumn?, row: Int) -> Any? {
    var showStr = "第\(row)行"
    if row%5 == 0 {
        showStr = "adsasdasfda第\(row)行狗幣鍵格的項吧goubigpp"
    }
    let attrDict = [NSAttributedString.Key.foregroundColor: NSColor.red]
    let attrStr = NSAttributedString(string: showStr, attributes: attrDict)
    return attrStr
}
func tableView(_ tableView: NSTableView, shouldEdit tableColumn: NSTableColumn?, row: Int) -> Bool {//可進行編輯
    return true
}
func tableView(_ tableView: NSTableView, toolTipFor cell: NSCell, rect: NSRectPointer, tableColumn: NSTableColumn?, row: Int, mouseLocation: NSPoint) -> String {//鼠標懸停在cell上顯示的提示文本
    return "tip\n大廈等級拉絲機\n的撒酒瘋拉薩附近阿里附近阿拉斯加阿克蘇交電費卡拉時間反饋時間的考慮"
}
func tableView(_ tableView: NSTableView, shouldShowCellExpansionFor tableColumn: NSTableColumn?, row: Int) -> Bool {//當列表長度無法展示完整某行數據時 當鼠標懸停在此行上 是否擴展顯示
    return true
}
func tableView(_ tableView: NSTableView, didClick tableColumn: NSTableColumn) {
    print("tableColumn.title", tableColumn.title)
    
}
func tableView(_ tableView: NSTableView, shouldSelectRow row: Int) -> Bool {
    print("row:", row)
    
    return true
}

@objc func clickTableView() {
    print("clickTableView")
}

(該NSTableView實例放置在ScrollView的documentView中)

• 方法1（NSScrollView -> NSTableView）
  對該NSTableView實例對應的NSScrollView實例視圖使用約束進行布局！（1層的約束）

func addTableViewJustScrollViewWithConstraint() {
    let scrollV = NSScrollView()
    self.view .addSubview(scrollV)
    scrollV.hasVerticalRuler = true
    scrollV.hasHorizontalScroller = true
    scrollV.hasVerticalScroller = true
    scrollV.translatesAutoresizingMaskIntoConstraints = false//添加約束
    let scrollV_Lead = scrollV.leadingAnchor .constraint(equalTo: self.view.leadingAnchor, constant: 100.0)
    let scrollV_Trail = scrollV.trailingAnchor .constraint(equalTo: self.view.trailingAnchor, constant: -100.0)
    let scrollV_Top = scrollV.topAnchor .constraint(equalTo: self.view.topAnchor, constant: 20.0)
    let scrollV_Bot = scrollV.bottomAnchor .constraint(equalTo: self.view.bottomAnchor, constant: -20)
    let scrollV_consArr = [scrollV_Lead, scrollV_Trail, scrollV_Top, scrollV_Bot]
    self.view .addConstraints(scrollV_consArr)
    scrollV.wantsLayer = true
    scrollV.layer?.backgroundColor = NSColor.red.cgColor
    
    let tableV = NSTableView(frame: scrollV.bounds)//NSTableView()//是否設置尺寸無所謂——下方放置到ScrollView的documentView中
    self.view .addSubview(tableV)
    scrollV.contentView.documentView = tableV//scrollV.documentView//將TableView放置到ScrollView的documentView中
    //不能添加約束——否則尺寸不能調整（寬不能調整）???
    //tableV.translatesAutoresizingMaskIntoConstraints = false//添加約束
    //let tableV_Lead = tableV.leadingAnchor .constraint(equalTo: self.view.leadingAnchor, constant: 0.0)

    //let tableV_Top = tableV.topAnchor .constraint(equalTo: self.view.topAnchor, constant: 0.0)
    //let tableV_Bot = tableV.bottomAnchor .constraint(equalTo: self.view.bottomAnchor, constant: 0.0)
    //let tableV_consArr = [tableV_Lead, tableV_Trail, tableV_Top, tableV_Bot]
    //self.view .addConstraints(tableV_consArr)
    
    tableV.wantsLayer = true
    tableV.layer?.backgroundColor = NSColor.cyan.cgColor
    tableV.delegate = self
    tableV.dataSource = self
    tableV.target = self; tableV.action = #selector(clickTableView)
    //添加列（必須）
    let column = NSTableColumn(identifier: NSUserInterfaceItemIdentifier(rawValue: "Colum-1"))
    column.width = 150//當前寬度
    column.minWidth = 100//最小寬度
    column.maxWidth = 200//最大寬度
    column.title = "column-No.1"
    column.headerToolTip = column.title
    column.resizingMask = NSTableColumn.ResizingOptions.userResizingMask
    tableV .addTableColumn(column)
    let column2 = NSTableColumn(identifier: NSUserInterfaceItemIdentifier(rawValue: "Colum-2"))
    column2.width = 150//當前寬度
    column2.minWidth = 100//最小寬度
    column2.maxWidth = 200//最大寬度
    column2.title = "column-No.2"
    column2.headerToolTip = column2.title
    column2.resizingMask = NSTableColumn.ResizingOptions.userResizingMask
    tableV .addTableColumn(column2)
}
