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 行的谷歌电子表格。如何在第 10 行下方插入新行。

我可以删除一行：

            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。看这里： https://developers.google.com/google-apps/spreadsheets/#modifying_a_worksheets_title_and_size

我想要一个如何在工作表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”，例如粗体。还有一些“有效”的单元格引用在下移时会出错，需要改成绝对引用。

代码

在插入行或删除行之后更新引用。这是最复杂的一点。 还有更多，但不容易拆分出来。
