Is it possible to make from an excel file (.xls) which
includes an
interactiv table to get values of a lense a wiki htm?
How to load an htm and than the excel file to wiki. if I try uploading it
says: no image.
You can upload excel spreadsheets, but you can't display them on the page AFAIK. You
have to use [[media:spreadsheet.xls]] instead of [[image:spreadsheet.xls]] on the page
though. This will provide a link for the file to be downloaded. See my sandbox for an
example
