nu-table/ Fix footer truncation in case of head_on_border (#13998)
Hi there; I do think it must be fixed. I also did improve performance for a fraction in case of header on border. I want to believe :) I didn't bench it. But we didn't cached the width in this code branch before. Which was causing all data reestimation. close #13966 cc: @fdncred
