问题
I'm creating a system that reads/writes a spreadsheet using PhpSpreadsheet. Does this library support the use of textboxes? When I tried all the textboxes were deleted.
回答1:
No, PhpSpreadsheet doesn't support any form elements; and features of Excel that aren't supported simply aren't loaded when the file is loaded, so don't exist in the spreadsheet object when it is saved
