hide colon in a repetition region

[Serviman]

Bye to all,
I created a table with a repetition region, ordered with a parameter that only useful to sort.
the column of the above is not interesting to the reader and I would like to hide it, but with my creo 2 I can not. I tried to search, but the only way is to delete the column, but losing the order created.
If it ever happened to you, how do you behave?
very small character?
white character, it doesn't work, I've tried, it's black...
very yellow character?
exists (see how much my sw has seen) a less clever and smarter system?

let me know and thank you in advance,

I know this problem.
I solved with a very small column and character.

Hi.

I always do it small and yellow. . .
I hoped it was a problem of my ignorance, thank you
