FTableRowBase

struct Engine Since 4.0

#include "Engine/DataTable.h"

Description

The required base struct for all data table row types. Subclass it with UPROPERTY-tagged fields to define the columns of a UDataTable.

Signature

struct FTableRowBase

Caveats & Gotchas

• Every UPROPERTY in the struct becomes a column in the data table. Properties must use types supported by the CSV/JSON importer.
• Override OnPostDataImport() to validate or fix up data after a reimport without modifying the source CSV.
• Structs used as row types cannot be nested inside classes — they must be at global scope with a USTRUCT macro.

Example

Define a data table row struct C++

USTRUCT(BlueprintType)
struct FEnemyRow : public FTableRowBase
{
    GENERATED_BODY()

    UPROPERTY(EditAnywhere, BlueprintReadOnly)
    float MaxHealth = 100.f;

    UPROPERTY(EditAnywhere, BlueprintReadOnly)
    float MoveSpeed = 300.f;

    UPROPERTY(EditAnywhere, BlueprintReadOnly)
    TSoftObjectPtr<USkeletalMesh> Mesh;
};
