如何使用 openxml 将现有的复杂行克隆到工作表

Question

我需要动态地将现有行克隆到工作表中。前任。我想复制第 28、29 行并插入到第 30、31 或 32,33 行，或者更多，这取决于数据行。 从

到

如何在 openxml 中动态地做到这一点？ 预先感谢。

Answer 1

最后，我使用EPplus而不是OpenXML， 只需 2 行即可解决我的问题。

private void AddRows(ExcelWorksheet sheet, int rowFrom, int colFrom, int rowTo, int colTo)
    {           
        sheet.InsertRow(rowFrom,2);
        sheet.Cells[28, 1, 29, 46].Copy(sheet.Cells[rowFrom, colFrom, rowTo, colTo]);
    }

Answer 2

在阅读了许多人说要插入行的帖子后，我发现这实际上在我的模板中造成了问题。插入行与在 excel 中插入不同/ 您实际上是在 xml 文件中插入一行，这意味着如果您不小心，行索引可能会乱序。以下代码是我用于模板的代码，我相信您可以修改它以满足您的需求。我会根据索引找到现有行并将其替换为我要复制的行。修改此代码以允许在找不到行时插入行，但我的模板没有问题，因此不需要比这更进一步。

希望这对像我一样被困在这个问题上几个小时的人有所帮助。
