Column on Table View is highlighted. Why?

I never seen this. Once I open the table view (on Edit/Table View), a column of the chosen table is highlighted in orange. What does that mean?

I guess because it might be a reserved word

Juan, you are right. It is a reserved word. More specifically, it is a database keyword. I changed the name of the column. Thanks!

For the forum. The list of the Reserved keywords is here:
