Can't view/edit a data table based on a C++ struct

I copied the wiki struct for C++:

struct FLevelUpData : public FTableRowBase


		: XPtoLvl(0)
		, AdditionalHP(0)

	/** The 'Name' column is the same as the XP Level */

	/** XP to get to the given level from the previous level */
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
		int32 XPtoLvl;

	/** Extra HitPoints gained at this level */
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
		int32 AdditionalHP;

After that, I tried to create a data table based on this. Created just fine, but upon opening it all I get is a blank window:

What am I doing incorrect here?

Okay, finally figured it out. Had to manually open the different parts of the window. The struct was working, just not “opening” with the data table window.

hei how u solve it?
I encounter the same problem
