The premise of intelligent table processing in Word is to extract the table structure and text information. By using visual studio tools for Office (VSTO) to obtain the extensible markup language (XML) information of the table, the structural relationship of the table and the text format of each cell can be further recognized. Compared with Visual Basic for Applications (VBA) technology, VSTO technology is slower in handling Word, but it has better extensibility and efficiency than VBA. VSTO technology can effectively recognize the structure of the table and extract information, providing possibilities for subsequent intelligent processing.
