DM-7594: Display phase column with 8 decimal places precision

[loitly]

https://jira.lsstcorp.org/browse/DM-7594
Also, add description meta to that column.

the displayed phase is now 8 decimal precision and the description appears too.

As the column is the last one in the table on the right-hand, the vertical scroll bar hide part of it. Is it possible to make the column wider so it shows the value (8 decimals) fully?

Minor (was in the ticket [DM-7595]: I've downloaded the table but i couldn't find any mention on the column 'phase'. Is it possible to add a comment with the column name 'phase' and the description as other columns?

I tried downloading the table. There is a comment with description of 'phase':

\ phase
\ ___ number of period elapsed since starting time.

Also, do you want to hide some of the columns by default?

About hiding columns, yes, probably we don't need all the columns, we can keep the fluxes, and time columns as first approach but i wouldn't change that until we get more details on those aspects.
For now is fine. Thank you!
Review done.
