put tableContent into field "Table Field"     -- put data into complete 
table
put field "Table Field" into tableContent     -- get complete table data

put empty into field "Table Field"

set the itemDelimiter to tab                                   -- the 
lines in a table field have the columns separated by tabs

put 6 into item 5 of line 7 of field "Table Field"   -- row 7, column 5
put item 3 of line 2 of field "Table Field" into mycell   -- row 2, 
column 3

not sure what you mean by this one?

Hmm, you could put the headings in another table immediately above the 
one they belong to, set the tabStops the same, eliminate the 
scrollbars, make it non-editable, and put a bit of code in the main 
field ("Table Field") to keep the horizontal scrolling in sync.  I did 
something like this with an experimental stack I had started at one 
point.

Then you could format the other table field however you want.
