Please ignore our previous update.
We can reproduce the reported text preservation problem in table in the Word document. We have faced conflicts (dependent code example missing) in the given code snippets. So, we have modified the code snippet to make runnable. Please find the sample which we tried at our end from the below link:https://www.syncfusion.com/downloads/support/forum/145803/ze/CreateWordSample538545617
Please refer the below screenshot of generated Word document using above sample.
After opened the generated Word document
When focusing on not fitted text.
On further checking with the reported problem, we have found after focusing on the particular text Microsoft Word viewer preserves the text properly in visual appearance and not found any changes in the file level for this preservation changes. This is not an issue in DocIO and it is problem when rendering contents by Word viewer.
Please let us know if you have any other questions.
