In my work, I often need to process the table content on the webpage. However, because of the casual nature of the table content during the process, cross-row and cross-column operations are often generated, I have made these functions, in order to get the table content, the important places in the program have been annotated, so I will not repeat the clarification here. after testing, it is very successful. so we can share it with you. // Author: Wang pengwu
