So, how can I suppress the printing of various error messages (like ones 
that say some particular evaluation produced an indeterminate result), 
while still using Check to replace the indeterminate (or otherwise 
erroneous) result with a chosen symbol, for example in a Table?

For instance if evaluating myExpression sometimes produces an integer 
and sometimes an indeterminate result, then using

   myResult = Check[myExpression, "*"]

helps make a Table column narrower than if it has to print out 
"Indeterminate" for each indeterminate result.
