问题描述
我正在尝试使用Open Office xml sdk填充Excel工作表中的超链接。
Excel工作表说明：
excel表包含3个表 -
•表1
•表2
•表3
表1和表3已包含一些数据和超链接。现在我想在excel表的表2中填充超链接和其他数据。
一旦我运行代码然后尝试打开excel表，我收到以下错误：
我们发现'Sheet.xlsx'中的某些内容存在问题。您是否希望我们尽可能多地恢复？如果您信任此工作簿的来源，请单击是。
单击是后，出现另一个错误：
Excel可以通过修复或删除不可读的内容来打开文件。
关闭此错误消息后，工作表数据变空。
然后我在excel表中进行了更改。
从表1和表3中删除了超链接，然后再次尝试在excel表的表2中填充数据和超链接。并且代码可以工作。
请建议我如何在excel表的表2中填充超链接，而不删除表1和表3中的超链接。
我使用以下代码：
//表单数据和超链接的方法
private bool PopulateHyperlink（SpreadsheetDocument myWorkbook）
{
#region变量
bool success = false;
Cell toolcelloffering = null;

I am trying to populate hyperlink in excel sheet using Open Office xml sdk.
Description of Excel sheet:
The excel sheet contains 3 tables –
•Table 1
•Table 2
•Table 3
Table 1 and Table 3 already contains some data along with hyperlinks. Now I want to populate hyperlink and other data in table 2 of excel sheet.
Once i run the code and then tried to open excel sheet, i am getting following error:
We found a problem with some content in 'Sheet.xlsx'. Do you want us to try to recover as much as we can?If you trust the source of this workbook, click Yes.
After click on Yes, getting another error:
Excel was able to open the file by repairing or removing the unreadable content.
And after closing this error message, sheet data gets empty.
Then I made changes in excel sheet.
Removed hyperlink from Table 1 and Table 3 and then again tried to populate data and hyperlink in table 2 of excel sheet. And the code works.
Please suggest how I can populate hyperlinks in table 2 of excel sheet without removing hyperlinks from table 1 and table 3.
I am using following code:
//Method to sheet data and hyperlink
