使用带有Java的API在Google电子表格中插入一行

Question

我有一个包含20行的google电子表格。如何在第10行下面插入新行。

我可以使用以下方法删除行：

            URL listFeedUrl = worksheet.getListFeedUrl();
            ListFeed listFeed = service.getFeed(listFeedUrl, ListFeed.class);

            ListEntry row = listFeed.getEntries().get(10);
            row.delete();

我可以通过调整工作表的大小在末尾添加一行。 请参阅此处： https : //developers.google.com/google-apps/spreadsheets/#modifying_a_worksheets_title_and_size

我想要一个如何在表格中间插入一行的示例。

Answer 1

API中没有“插入”。 解决方案是手动向下移动行以创建间隙。 这不会移动“样式”（如粗体）。 并且某些“有效”单元格引用在向下移动时会导致错误，需要将其更改为绝对引用。

码

在插入行或删除行之后更新引用。 这是最复杂的部分。 还有更多，但不容易拆分。
