在NstableView中选择时Nstextfield对齐

Question

我有一个编程创建的NstableView，其中n行和1列。嵌入式文本字段是可选的，而不是可编辑的。我能够观察文本字段中的Mousedown事件，但是如您在图像中所看到的，所选行是重新定位并包装了单词。我怀疑这可能与现场编辑有关，但是我的Macos Odyssey证明了我无数的错误时期。

我的问题：我需要做些什么来维护所选行的布局以与表中的其他行保持一致？

更新：添加textfield.cell.wraps = false forse tobleview委托消除了单词包裹，但仍然存在所选文本字段的问题。

代码片段：
从表委托：

    func tableView (_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) -> NSView?
    {
        let text = dataArray [row]
        var v = tableView.makeView(withIdentifier: NSUserInterfaceItemIdentifier.init(rawValue: "TableColumn"), owner: self) as? MyTextFieldExt
        if v == nil
        {
            v = MyTextFieldExt ()
            v?.identifier = NSUserInterfaceItemIdentifier(rawValue: "TableColumn")
            v?.maximumNumberOfLines = 1
            v?.autoresizingMask = [.width]
            v?.setContentHuggingPriority(NSLayoutConstraint.Priority(rawValue: 251), for: .horizontal)
            v?.translatesAutoresizingMaskIntoConstraints = false
            
            v?.isEditable = false
            v?.isSelectable = true
            
            v?.cell?.wraps = false
        }
        
        v!.stringValue = text
        v!.font = NSFont.monospacedSystemFont(ofSize: 10, weight: .regular)
        v!.frame = CGRect(x: 0, y: 0, width: 3000, height: 0)

        return v!
    }

从捕获Mousedown的文本字段（自定义）：

    override func mouseDown(with event: NSEvent)
    {
        super.mouseDown(with: event)

        let cEditor = self.currentEditor() as? NSTextView
        let localPos = convert (event.locationInWindow, to: nil)

        let location = cEditor?.selectedRange().location

        if let r = cEditor?.selectedRange()
        {
            self.select(withFrame: self.frame, editor: cEditor!, delegate: self, start: r.location, length: r.length+10)
        }

    }

从创建scrollview，表观和列的视图控制器：

    func setupTableView ()
    {
        let tableView = MyTableViewExt ()
        tableView.selectionHighlightStyle = .none
        
        tableView.headerView = nil
        tableView.columnAutoresizingStyle = .lastColumnOnlyAutoresizingStyle
        tableView.autoresizesSubviews = true
        tableView.autoresizingMask = [.width, .height]
        
        let column = NSTableColumn ()
        column.identifier = NSUserInterfaceItemIdentifier(rawValue: "TableColumn")
        column.width = 426
        column.minWidth = 40
        column.maxWidth = 1000
        column.resizingMask = [.autoresizingMask, .userResizingMask] // verify in debugger
        
        tableView.addTableColumn(column)

        tableView.delegate = self
        tableView.dataSource = self
        
        let scrollView = NSScrollView (frame: self.view.bounds)
        scrollView.autoresizesSubviews = true
        scrollView.autoresizingMask = [.height, .width]
        scrollView.translatesAutoresizingMaskIntoConstraints = false        
        scrollView.hasHorizontalScroller = true
        scrollView.hasVerticalScroller = true
        
        self.view.addSubview(scrollView)
        
        self.view.addConstraint(NSLayoutConstraint (item: self.view, attribute: .trailing, relatedBy: .equal, toItem: scrollView, attribute: .trailing, multiplier: 1.0, constant: 20))
        self.view.addConstraint(NSLayoutConstraint (item: scrollView, attribute: .leading, relatedBy: .equal, toItem: self.view, attribute: .leading, multiplier: 1.0, constant: 20))
        self.view.addConstraint(NSLayoutConstraint (item: self.view, attribute: .bottom, relatedBy: .equal, toItem: scrollView, attribute: .bottom, multiplier: 1.0, constant: 20))
        self.view.addConstraint(NSLayoutConstraint (item: scrollView, attribute: .top, relatedBy: .equal, toItem: self.view, attribute: .top, multiplier: 1.0, constant: 20))
        
        scrollView.documentView = tableView
    }

因此，通过修改文本字段Mousedown逻辑中的代码来解决我的问题。校正的代码看起来像这样，并且在设置选定范围的设置时会发生变化：

    override func mouseDown(with event: NSEvent)
    {
        super.mouseDown(with: event)

        let cEditor = self.currentEditor() as? NSTextView
        let localPos = convert (event.locationInWindow, to: nil)
        let insertionPoint = cEditor?.characterIndexForInsertion(at: localPos)
        let location = cEditor?.selectedRange().location

        if let r = cEditor?.selectedRange()
        {            
//          self.select(withFrame: self.frame, editor: cEditor!, delegate: self, start: r.location, length: r.length+10) <-- Source of problem
            cEditor?.setSelectedRange(NSMakeRange(r.location, r.length+10)) <-- Solution to problem
        }
    }

而且要明确，不需要textfield.cell？cell？.wraps = false i在评论中做出的陈述是不正确的。在我的表观视图委托中需要该行以避免包裹一词。
