Using an HTML Table element for the initial TreeView implementation has been very beneficial since it allowed us to inherit the elastic resizing of columns.
We reached a point where the DOM reflow performance is affected by the table structure.
Now that we have many tests and good performance for the current widget, we can explore its rebuild with simple divs.
