Node-red-node-ui-etable trouble

Hi folks!!
I'm trying to transpose a table (etable node) but not seeing results...
I was able to create a table in html and then transpose it with a template node:

tr { display: block; float: left; } th,td { display: block; }
name number
Giulio 1
Gianna 6

(Maybe it's not the right way to append a code....).

I think (it's a mere assunption) I should write the reference to my table rows inside the style tag, rather than the tr,th,td of test table.
Thanks in advance.
Regards.
