Write New Query to return Maximum Date from table

[Syndicate_Admin]

I trying to create a list of Dates table from another table.  I would like to extract from the other table the maximum and minimum dates in the table.  I could just use the table and find the values but I don't want the extra code that was required to add the original Dates.  I need help in writing the query.    This is what I tried:

= Table.Column(#"Case List",maximum([End Date])) 

= Table.Column(#"Case List",([End Date]))

Use this:

List.Max(#"Case List"[End Date])
