Crosstab/Pivot queries. How can I edit using Apex?

Question

Hello, all.
I currently have a report within Apex that displays the results of a crosstab/pivot query as shown below. This works fine.
What I now need to do is provide edit functionality on each row. The row does not have an individual ID column per sé as each row is the result of the crosstab query.
What is the best way to offer the edit functionality using Apex?
Thank,
S>

Hello, Steven
Maybe you can use collections for that.
Create a new collection which store your select statement.
Each member of the collection have a unique id so you can use edit functionnality.
And create a PL/SQL process which update your original table when the elements
of your collection is updated.
You can look at this doc. It may be useful.
