Is there a "prefered" way to access data in a table?
T.var1(1);
T{1,var1};
T{1,1};

+1 to Stephen, however, T{1,var1} would have to be T{1,'var1'}. Also, while I find T.var1(1) easier to follow than t{1,'var1'}, once you get to accessing the data in more than one variable in a table all at once, braces are the way to go: T{1,{'var1' 'var2'}}.

If you are importing from a csv or xls or xlsx, then a question becomes which you trust to be more accurate as files change: column number, or column header.
Some "standard" formats (even if only unofficial standards) define information according to column; others define by column names.
If your users expect to be able to insert columns at arbitrary points as long as they keep the column headers the same for what is already there, then you should probably be using column name.
