透视表配置项如链接所示（链接的渲染和项目本地实际渲染结果不同，所以仅用来参考配置，实际效果我会额外截图）

### 😊 Expected Behavior
树模式下列总计可以正常展示

### 😅 Current Behavior
树模式下列总计展示异常

Start with the linked CodeSandbox entry point at index.ts:16 and review the PivotSheet configuration, especially the custom calcFunc for column totals. Reproduce the tree-mode case and compare the calcFunc spreadsheet value and rendered totals with the expected behavior. Done means custom column totals display correctly in tree mode.
