如何提取幻灯片表格
Apps in the Google Suite (Docs, Sheets, and Slides) keep track of all the edits, changes, and versions of a file so you can revert to an earlier version if you need to. Here’s how to do it.
Google Suite中的应用程序(“文档”，“表格”和“幻灯片”)会跟踪文件的所有编辑，更改和版本，因此您可以根据需要恢复到较早的版本。 这是操作方法。
First, open up a file you have stored on Google Docs, Sheets, or Slides. We’ll be using Google Docs, but the process is the same on the other two services as well.
首先，打开您存储在Google文档，表格或幻灯片中的文件。 我们将使用Google文档，但其他两个服务的过程也相同。
Open the “File” menu, click the “Version History” submenu, and then click the “See Version History” command. Alternatively, you can press Ctrl+Alt+Shift+H.
打开“文件”菜单，单击“版本历史”子菜单，然后单击“查看版本历史”命令。 或者，您可以按Ctrl + Alt + Shift + H。
Note: If you don’t have edit permissions for a file, you won’t be able to view the Version History section of a file. This won’t be a problem if you created the file, of course.
注意：如果您没有文件的编辑权限，则将无法查看文件的“版本历史记录”部分。 当然，如果您创建了文件，这将不是问题。
Versions of a file are grouped with related changes on the right side of the window. Depending on how meticulous you are, they might have proper names, or they could just be sorted by the time you created them. Each version is a collection of edits that are grouped and merged based on the age of the file or the size of each version. This is done to save storage space on Google’s servers.
文件的版本与相关的更改分组在窗口的右侧。 根据您的细致程度，它们可能具有适当的名称，或者可以仅在创建它们时对其进行排序。 每个版本都是编辑的集合，这些编辑根据文件的使用期限或每个版本的大小进行分组和合并。 这样做是为了节省Google服务器上的存储空间。
Clicking a specific version will temporarily revert your file to that state in the main window to the left. It will also display the changes that were made along with who made them.
单击特定版本将在左侧主窗口中将文件暂时恢复为该状态。 它还将显示所做的更改以及进行更改的人员。
To get an even more granular view, click the chevron located next to a version and then click a specific event to view that version.
要获得更详细的视图，请单击版本旁边的人字形，然后单击特定事件以查看该版本。
Once you’ve decided on a version you want to switch back to, click the “Restore This Version” button at the top of the window.
确定要切换回的版本后，请单击窗口顶部的“还原此版本”按钮。
A pop-up will warn you that your document is about to be reverted to a different version. Click “Restore.”
弹出窗口会警告您您的文档将被还原为其他版本。 点击“还原”。
If you aren’t happy with the restored version of your file and want to go back to a previous version, don’t worry; all is not lost. Google won’t automatically erase anything. Instead, it makes a copy of the version you selected and makes it the current one. Head back to Version History by pressing Ctrl+Alt+Shift+H. From here, repeat the previous steps to restore your file back to the previous one, which should be located near the top of the list.
如果您对文件的还原版本不满意，并且想返回到以前的版本，请不要担心。 一切都不会丢失。 Google不会自动删除任何内容。 相反，它会复制您选择的版本并将其作为当前版本。 通过按Ctrl + Alt + Shift + H返回版本历史记录。 从这里开始，重复前面的步骤将文件还原到上一个文件，该文件应该位于列表顶部附近。
