For long tasks, the pegasus-statistics columns are too narrow:

add_replace 2 2 0 3826.494 4192.534 4009.514 8019.028
alignment_to_reference 2 2 0 117730.84 119376.044118553.442237106.884
combine_variants 1 1 0 425.118 425.118 425.118 425.118

My suggestions:

1. Drop the partial seconds - there is no reason for reporting this down to 1000s of second.

2. Switch the units for table automatically based on the runtimes, but keep all the values in the same unit.

3. Make the columns autosize.

4. Right justify the columns with numbers
