We should consider cases in which the fraction or speciation is not populated when joining the criteria table to the TADA data frame.
Would it be useful to indicate all unique TADA.CharacteristicName(s) that may not be matched during this tab? Tab 2 attempts to flag any cases in which there are invalid values within a column, but it may also be useful to show in bold text for any missing TADA.CharacteristicName(s) if they cannot be matched.
