Hello aleksandra_budnik;
Thank you so much.
I am writing the DB side to be able to complete the test.
Parameters, data types, xml, Oracle pl / sql packages, … etc.
My coding took too long. I can finish tomorrow.
There are already many features on the Handsontable grid side. (calculations, subtotals, …)
The first subject I will study:
1 - Open popup form while in cell and search live in DB.
2 - When the popup form is closed, write the search result in the cell next to it.
Good work.
