@alien4u if its editable sublist, you could add/remove lines, but that might bring performance issues, dont think SS1.0 supports it, and idk about SS2.0, you should check the doc there. For a different project I had to filter and sort a list in suitelet and due to netsuite sublist limitation I instead picked a javascript lib that transform a static html table into a dynamic table (sort (number or date or string) /filter (by distinct value, formulas, group), automated styling with alternate colors on each line, etc) https://github.com/koalyptus/TableFilter some other issues to get it working, but it does a lot of things automatically. It won't have the styling of netsuite, but doesn't look too bad for what it does.
