What was bob ewells appearance on the stand in chapter 17 to kill a mockingbird

I'm not exactly sure what you are asking here. Mr. Ewell is surly and crass in the witness chair, but the judge, who clearly does not respect the man, manages to keep everything orderly. Mr. Gilmer asks Mr. Ewell for his version of the events. Mr. Ewell claims that he heard Mayella screaming when he was coming in from the woods with kindling, and that he ran to the house to find Tom Robinson having sexual intercourse with her. He uses the highly offensive term "ruttin," which causes an uproar in the court. After the judge calms everyone down, Mr. Ewell says that he ran to get the sheriff. He implores the judge to "clean up" the "nigger-nest" that are his neighbors, claiming that his neighborhood is getting dangerous.
