I tried inserting a RowFilter into my table and it worked, so long as the filter argument matched the case in the column.
This successfully returned the rows containing "Alternator" in the Parts column. But, if I change the filter to "alt" then I do not get a hit. I tried entering Pattern.CASE_INSENSITIVE into the filter (see below), it compiles but when I execute the code no rows are returned. I checked the Java documentation on RowFilter, and there is nothing about how to set expression flags. I also tried replacing "alt" with a pattern, but that wouldn't compile.
