在表中显示javascript数组，在数组中显示平均分数

I'm having some trouble with creating a table with different tr's and td's from an array in javascript. I can get the scores and names to display in the displayScores function, but the values aren't in their own separate cells. I'm also having some trouble getting the displayResults function to show the proper average when I add a score and name to the array. The right "highest score" will show but the added scores don't get averaged. Any help with any of the problems I'm having would be greatly appreciated. I'm having some trouble with creating a table w
