Define Top N by multiple columns

[NOVICE02]

Hi,
Hoping for some direction. Never done this before and in a time crunch

I have a table of names with certain measures like below. there are 100's of names. I need to highlight the Top N names. First by C%, then d% then r%

is it possible to do this? and change the ordering depending on the ask. the measures would remain the same,

Name	C%	d%	r%
tt	20%	45%	25%
tr	10%	55%	24%
rt	5%	75%	26%

Seems than is enough the only Table.MaxN function to get the expected result, when the values are positive:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("bZLLDcQgDER7QdpbDtg4fGqJ0gSify3YbDRhuVhiXmZiY67LteYOx/7Tq5yjcq/30UHtB1JwGhADdThUSabHaRh62Oh10RPkbHTrKALIGKQOkoxEo4SURP2AC4TtSV1J8JBm0kLaPyFI2xJNyxEJgycnu3RBop4yb1EnHWM/HZBnm55eSBdmG/shXNlEwRdEDRFbf68XENh+kh50fwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Name = _t, #"C%" = _t, #"d%" = _t, #"r%" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"C%", Percentage.Type}, {"d%", Percentage.Type}, {"r%", Percentage.Type}}),
    besten = Table.MaxN(#"Changed Type",{"C%"},10)
in
    besten

Hello @NOVICE02 

I don't know if I get you right. Check out this solution. Depending on the variable "Task" the table is sorted differently. Just change the variable "Task" accordingly to change the result.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WKilR0lEyMlAFkiamINIISMbqACWKgBxDsIQpRMIEIlEE0gEWMYeImwHFYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Name = _t, #"C%" = _t, #"d%" = _t, #"r%" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Name", type text}, {"C%", Percentage.Type}, {"d%", Percentage.Type}, {"r%", Percentage.Type}}),
    //Variable for ordering c, d or r allowed
    Task = "d", 
    Top2N = if Task = "c" then 
        Table.FirstN(Table.Sort(#"Changed Type", {{"C%", Order.Descending}}),2) else
        if Task = "d" then 
        Table.FirstN(Table.Sort(#"Changed Type", {{"d%", Order.Descending}}),2) else
        if Task = "r" then 
        Table.FirstN(Table.Sort(#"Changed Type", {{"r%", Order.Descending}}),2) else "wrong task variable"
in
    Top2N
