I am currently trying to add colors to cells in a table based on the value in the cell. I am trying to build a workflow with web widgets, so that the users can download the file with color from the web portal.
I came across the workflow in the link- Add Colors to Table Cells – KNIME Community Hub. And this helps to see the cells with color with table view widget.
Is there a way to save/download(using file download widget) the table as a excel file with the colors?
I also tried this workflow, but this can’t be used in the webportal, it only can be executed in local version. I tried connecting a file download widget in the end, but it doesn’t do the job.
Could you provide me with an alternative solution?
Thanks in advance,
Hi @AkshayPrakash, welcome to the community!
You are perfectly on the right track already. There are two “modes” to distinguish, for each you’d have to do the coloring separately:
- Coloring the Table View - there you already found the perfect example on how this works. I’d use this for a workflow with web widgets (i.e. a DataApp)
- For coloring the Excel File you also found the perfect example already - just as you already figured, you can then provide the Excel File via the File Download Widget. Why can’t it be executed on a non-local environment (on a KNIME Server?)? Most likely, the Continental Extension is missing there. This is something your KNIME Server Admin can take care of.
Hope that still helps!
