This fixes the scrollto / back to the top issue for row select:
(draggable blocks)
Ok if I understand correctly just change from this (V4):
to this (V6):
And that's it!
(I think the for cycle is unnecessary, my table has up to 1000 rows and it may lag?)
Anyway thanks for your time! All problem solved!
I hope many will benefit from it

Without the first part, you can end up with many selected/highlighted rows on your table.
You could add to the javascript/blocks, to capture the last selected row, and just clear the background for that.

Good morning, I have a query that displays a laboratory reservation in a ListView, this part works fine but I want to display the same information in a TableViewer. I have these blocks, but it doesn't load anything in the list called ListaTabla or in the TableViewer... I'm not sure if I'm adding each record correctly to the table called ListaTabla... I hope someone can help me... thank you.
run "DO IT " on ListaTabla, tell us what it shows.
And I did not see "TableViewer.Init" block, did you call this at other place?

Hmmm, from your blocks it looks like you are trying to create a single column list. You will need to make a list of lists for this.

That was the solution, dear KevinKun... Thank you very much for it.
Friend, I don't know what changed, but now it's not showing me the information in the Table... the information is coming through fine in the ListTable. 
I already discovered what the problem was... I had the table defined incorrectly."
hello @Kevinkun , have a nice day ahead!
I want to ask about how to remove the background color of the previous row when you click a new row. I am having a problem when I click a row, the background color of the previously selected row remains.
Here is the app screenshot:

Hoping for your kind response and thank you in advance..
You need a variable to store row number of last time you clicked.
Please read this thread completedly, there is some examples for this .
