I have a docx template and it has some place holder. It also has a table in it with a header row and the next row has place holder strings. I was successful in replacing the text and also add rows inside the table. Now I need to replace a placeholder inside a table cell with html content. However, I could only replace with HTML content outside the table, but not inside the table cell. Please help.
