Does it allow specifying columns when filtering for rows?

For instance, the shown example filters for "Bug" but seems to filter for rows that contain "Bug" in any of the columns. Can I specify to filter for "Bug" only looking at a certain column?

At the same time - is filtering by numbers implemented, like filtering for rows that have a numeric value above X in a certain column?

If not these should be on TODO list - those are very common operations for .csv type data.
