所以,我正在使用Visual Studio 2010,在过去一周或者我收到来自Visual Studio的消息:"Visual Studio遇到了异常.这可能是由扩展引起的."

我的ActivityLog.xml显示将此问题记录为:

使用OpenXML SDK将边框应用于合并的单元格区域时,边框仅显示合并范围中的第一个(左上角)单元格.我完全不知道,这让我发疯.使用生产力工具,我找不到任何有意义的差异,我有什么和预期的工作.这是我为样式表生成的XML:

    <x:borders count="2" xmlns:x="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
      <x:border>
        <x:left />
        <x:right />
        <x:top />
        <x:bottom />
        <x:diagonal />
      </x:border>
      <x:border>
        <x:left />
        <x:right />
        <x:top />
        <x:bottom style="thick">
          <x:color auto="1" />
        </x:bottom>
        <x:diagonal />
      </x:border>
    </x:borders>
    <x:cellXfs xmlns:x="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
      <x:xf fontId="0" />
      <x:xf fontId="1" fillId="2" applyFont="1" applyFill="1" />
      <x:xf borderId="1" applyBorder="1" />
    </x:cellXfs>

我已经尝试了一切,在边界之前,之后等应用合并.

所以我试图测试一个主题的行为，但它不起作用，而且似乎有些事情我没有正确理解。考虑以下测试：

it('marble testing subject test', () => {
    const obs$: Subject<number> = new Subject<number>();

    obs$.next(42);
    obs$.next(24);

    expect(obs$.asObservable()).toBeObservable(hot('xy', { x: 42, y: 24 }));
  });

这失败并显示以下错误消息：

Expected $.length = 0 to equal 2.
Expected $[0] = undefined to equal Object({ frame: 0, notification: Notification({ kind: 'N', value: 42, error: undefined, hasValue: true }) }).
Expected $[1] = undefined to equal Object({ frame: 10, notification: Notification({ kind: 'N', value: 24, error: undefined, hasValue: true }) }).

我想我有点明白为什么：（Subject每个文档）只在订阅开始后发出值。该toBeObservable()函数（我假设）订阅了Subject …
