                # (more specifically, handling the line rows above?)

                row_index = 0

thought for the future:

the reason for having each frame fully stringify itself and have to_string only handle the lines between frames was an attempt to balance to three considerations:

• the dividing line can only be drawn when the frames both above and below are known ( so in to_string )
• the original idea to leave padding and outer borders to to_string and the rest in the ... would be complicated because of the table row lines interacting with outer borders
• reducing load on the to_string method to ensure smooth printing (perhaps not necessary... perform time tests)

maybe in the future it would be better to treat each row of the table as a frame and have to_string stringify everything

probably this will be less confusing and better unify concerns

new_to_string & new_add_ methods... to perform A/B tests

performance vs clean code...

(thought: perhaps the end of each add_ function could render all above??? could get messy...)

maybe perform speed test in constrained VM/container

finish everything else before doing this... (so not having to go too far back in time in case want to undo later...)

NOTE: currently... the table row lines are generated only once and reused...

one solution would be to define the line types... whether divider or text (so border can be correctly rendered) => too many checks (specific only for table...) in to_string

the trick is that there is so much logic specific to tables... => blank dividers for instance (actually this would not be a problem since this doesn't affect the row divider)

current timings:

• add_table = 0.119ms
• to_string = 0.047ms
• print = 0.014ms
• row_frame_divider = 0.006ms

---

• for 20 row table, row_frame_divider would cost 0.12ms (vs 0.006 currently)
• for 100 row table, row_frame_divider would cost 0.6ms (vs 0.006 currently)

---

conclusion: leave as is until a best of both worlds (clean and performant) solution can be found... the performance differences are too great.
