Daily Unreal Column #53 - Filter Data Table

Data table is a generic type that takes a struct that defines its row layout. Here is how to filter them by row type in the editor.

When you make a blueprint exposed UPROPERTY like this:

UPROPERTY(EditAnywhere)
TObjectPtr<UDataTable> MyDataTable;  

Once you open the editor and try to assign a value to this property, you will immediately notice that all existing data tables are shown. Which in most cases is NOT what you want, because you expect a data table with a specific row type definiton.

To make Unreal editor filter the displayed data table to only show the ones with a specific row type, you need to update the declaration of the property to match the following:

UPROPERTY(EditAnywhere, meta = (RequiredAssetDataTags = "RowStructure=/Script/GameName.YourRowType"))
TObjectPtr<UDataTable> MyDataTable;

where YourRowType is the name of the struct that defines the row type of your data table.
