Looking at the image, I can see the film review record page with a table showing joint numbers (1-C1-C4, 2-C1-C4, 3-C1-C4). The red arrow points to the operations column where I need to add an "insert row" button next to the existing delete button.

Now I need to find the addRow and removeRow functions to understand the pattern, then add an insertRow function:

Now I'll add the insertRow function and the insert button. First, let me check what icons are imported:

Now I'll add the insertRow function after removeRow and update the imports to add an insert icon:

Now add the insert button next to the delete button in the operations column:

Also need to widen the operations column to fit both buttons:

Added an "insert row" button (using ArrowUpToLine icon in blue color) to the operations column in the film review details table. When clicked, it inserts a new empty row before the selected row. The operations column width was also increased from w-12 to w-20 to accommodate both the delete and insert buttons side by side.

This is a significant task that requires creating a sidebar navigation and a complete MT工作台 with different form fields. Let me plan and implement this systematically.

Now I have a good understanding of the structure. Let me start implementing. First, I'll create the sidebar layout component:

Now let me create the MT mock data and types:

Now I'll create the MT commission form component based on the PDF specifications:

Now I'll create the MT film review modal with 4 tabs (委托单、检测记录首页、检测记录结论、返工通知). This is a key component based on the PDF document:

Now let me create the MT Inspection Conclusion component:

Now create the MT Rework Notice component:

Now create the MT Commission Detail View and the MT Film Review Modal:

Now create the MT Film Review Modal:

Now I'll create the MT workstation page component that includes all the tabs (委托办理、委托查询、探伤办理、探伤报告):

Now I need to update the main page to integrate the sidebar and both workstations. I'll also create a separate RT workstation component for better organization:

Now update the main page to use the sidebar and both workstations:

我已完成MT工作台的原型实现，主要包括以下内容：

1. 侧边菜单栏 (sidebar-layout.tsx) - 可收起的侧边导航，包含RT工作台和MT工作台两个菜单项
2. MT数据类型和模拟数据 (mt-mock-data.ts) - 定义了MT委托、检测记录、检测结论、返工通知等数据类型，以及所有下拉选项配置
3. MT委托表单 (mt-commission-form.tsx) - 按照PDF文档中的"超声波检测委托书"样式，包含选择焊缝信息表格、工件结构示意图等

4. MT评片记录模态框 (mt-film-review-modal.tsx) - 95%宽度100%高度的弹窗，包含四个页签：

   • 委托单 - 查看委托详情（只读）
   • 检测记录首页 - 磁粉检测记录表单，包含磁化方法、仪器型号、磁粉种类等字段
   • 检测记录结论 - 检验记录表格，支持缺陷记录表（II/III/IV级时显示）
   • 返工通知 - 显示缺陷情况，无返工时显示"无返工内容"
5. MT工作台页面 (mt-workstation.tsx) - 包含四个页签：委托办理、委托查询、探伤办理、探伤报告，样式与RT工作台一致

所有表单字段均按照PDF文档中的说明进行配置，包括默认值、下拉选项、可编辑/不可编辑状态等。
