Table visualization and case sensitivity
Happy New Years Day!
Add custom column, not conditional column.
Conditional Column options are too basic to handle List.Contains or invisible characters.
Then paste into the custom column window:
if List.Contains(List.Transform({97..122}, each Character.FromNumber(_)), Text.Start([DATABASE_NAME], 1)) then Character.FromNumber(8236) else ""
I'm assuming your column is named [DATABASE_NAME], but if not, then substitute the right name.
Basically...
List.Contains({a..z}, "e" is true.
List.Contains({a..z}, "E" is false.Fred
Power Query is case sensitive, so you could remove duplicates there and add an index as a unique id. In most regions, DAX is case insensitive, so it would be good to have a unique identifier.
Table visualizations have a related problem, in that they cannot show rows with duplicate data. So, if you have a check detail with 2 separate line items of $26.99 for different items with the same description, it will display only one row. You would have to include the order line number as well. The idea to prevent this kind of aggregation is here.

Thanks Fred, that is what I was presuming.
Seems like a pretty serious shortfall imo.
I can add an index to get both rows, but still will not be able to display the apprropriate values as they both show up the same.
Yes, I could add other fields as well but that's not really the point.
I see what you mean now! Here are two ways to force the lowercase to appear. One is by appending the index to the name. The second is to append an invisible character to the name if the name is first letter is lowercase. Appending a space at the end won't work.
In Power Query, I add a custom column for invisible space if the first character of the name is lowercase.
if List.Contains(List.Transform({97..122}, each Character.FromNumber(_)), Text.Start([Column1.1], 1)) then Character.FromNumber(8236) else ""
97-122 are the ascii characters for lowercase letters. 8236 is an invisible character.
I then append the Lowercase Space column to the database name.
An alternate way is to pad the start of the name based on the index value:
Text.Repeat(" ", [Index]) & [Column1.1]
The table visualization strips out leading spaces, but still sees the values as unique.

Thanks again Fred, this looks promising!!
I'm a newbie so the syntax adding this conditional column using the list.contains is confusing me and giving me errors.
I'll play around with it more after the Holidays
Thanks and have a great New Year's Day.
