Prompt: - In the tableau page (src/pages/tableau.py), I want to allow users to copy a URL in their clipboard that enables opening the page with the same view: applied filters, sorting and column selection of the datatable. Typically to share the view with a colleague via email or chat.
In terms of Dash callbacks, that would mean the following:
- one callback syncs the filters, the sort parameters and the selection of columns with a read-only text input that stores the URL to copy. This callback also ensures the button to copy to the clipboard is visible, possibly replacing the confirmation message (see next point)
- one callback reacts to clicks on a button to store the URLin the clipboard. This button in on the same row as "Télécharger au format Excel" button. When clicked, the URL is stored in the clipboard, and the button is replaced with a confrmation message (URL copiée)
- one callback reads the URL, and applies the filters, sorting and column selection
- The URL stores the view configuration (filters, sorting and columns) in URL parameters, similar to what is done in REST APIs. The values are the same as stored in the DataTable parameters, just URL encoded. The URL parameters are in French: filtres, tris, colonnes.
