How to import web table content into excel_javascript skills

//Export to Excel, note that there must be no comments in the table mark, because the childNodes will also count the comments
//If an error occurs, you need to close Excel, otherwise the Excel process will keep running
//There can only be one input value in td
//There cannot be a structure in non-td, otherwise a missing ";" error will be reported
//Add
//Add button
//Set the id and class of the table table to tableNr
