Aggregate table columns in [t] in the table {[t = {[a=1, b=2, c=3], [a=2,b=4,c=6]}, b = 2]} into the sum of [t.a], the min and max of [t.b], and the count of values in [t.a].

// Output: Table.FromRecords( {[#"sum of t.a" = 3, #"min of t.b" = 2, #"max of t.b" = 4, #"count of t.a" = 2, b = 2]} )
                t = Table.FromRecords( {
                    [a = 1, b = 2, c = 3],
                    [a = 2, b = 4, c = 6]
                } ),
                b = 2
        type table [t = table [a = number, b = number, c = number], b = number]
        {"a", List.Sum, "sum of t.a"},
        {"b", List.Min, "min of t.b"},
        {"b", List.Max, "max of t.b"},
        {"a", List.Count, "count of t.a"}
