【问题描述】：

如何为以下视图减少表单上各部分之间的间距？

    var body: some View 
            Form 
                Section 
                    TextField("Name", text: $patient.name, onEditingChanged:  changed in
                        if !isNewPatient 
                            isSaveDisabled = false
                        
                    , onCommit: 
                        if !isNewPatient 
                            isSaveDisabled = false
                        
                    )
                    .validation(patient.nameValidation)
                    TextField("Surname", text: $patient.surname)
                        .validation(patient.surnameValidation)
                    TextField("ID Number", text: $patient.id)
                        .validation(patient.idValidation)
                        .validation(patient.idRegexValidation)
                        .disabled(!self.isNewPatient)
                        .foregroundColor(isNewPatient ? .black : .gray)
                
                Section 
                    TextField("Street Number and Name", text: $patient.street)
                    TextField("Suburb", text: $patient.suburb)
                    TextField("Area Code", text: $patient.postCode)
                        .validation(patient.postCodeRegexValidation)
                .isHidden(isDependant, remove: true)
                Section 
                    Picker("Medical Aid", selection: $patient.medicalAidName) 
                        ForEach(medicalAids, id: \.self) 
                            Text($0)
                        
                    
                    TextField("Medical Aid Number", text: $patient.medicalAidNo)
                .isHidden(isDependant, remove: true)
                Section 
                    Button("Save") 
                        if isNewPatient 
                            if patient.create(moc: moc, isDependant: isDependant, mainID: self.mainID) 
                                isDependantsActive.toggle()
                            
                         else 
                            if patient.update(moc: moc) 
                                self.presentationMode.wrappedValue.dismiss()
                            
                        
                    .disabled(self.isSaveDisabled)
                
                NavigationLink("Dependants", destination:
                                DependantListView(filter: mainID).environment(\.managedObjectContext, moc), isActive: $isDependantsActive
                ).disabled(isNewPatient).isHidden(isDependant, remove: true)
            
            .onReceive(patient.allRequiredValidation)  validation in
                if isNewPatient 
                    self.isSaveDisabled = !validation.isSuccess
                
            
            .navigationBarTitle(title, displayMode: .inline)
    

这是表单的外观：

我查看了以下答案，但它们是不可接受的： Spacing between sections in a form

【参考方案1】：

尝试在包含Form的View中添加以下内容

init() 
    UITableView.appearance().sectionHeaderHeight = .zero

【讨论】：

它可以工作，除非该部分有标题，在这种情况下没有变化。
