Micheal,

I hate to remind you of the fact that English isn't my mother 
language. I prefer to speak here  language of codes. Otherwise, 
I'm afraid there would be a lot of misunderstanding.
But, nevertheless I'll try.
I don't think the table is essentially paper based presentation. Yes, 
such abstractions as n-dimension arrays (n>3) are hard for students 
to understand and "feel". But vectors and matrixes aren't as 
difficult. I haven't worked much with arrays in Logo yet, but it was 
quite simple for me to teach these things in Pascal. Speaking about 
matrixes I asked the students to imagine a concert hall, where every 
sit is defined by two numbers. I don't think I had to pay 
their attention to such things as how the array is presented in 
memory.   And on the level of understanding programming there was no 
serious problems.
And  when the students  are working with databases or spreadsheets 
they are dealing with the tables, not with the lists...

I'm not sure, all this makes any sense, sorry :-)

Olga.
