我的需求：在UE4游戲工程里建立4種自定義表格
參考文檔: UE4.11 引擎自帶的代碼文件 GameplayTagsManager.h

/** Simple struct for a table row in the gameplay tag table */
USTRUCT()
struct FGameplayTagTableRow : public FTableRowBase
{
    GENERATED_USTRUCT_BODY()

    /** Tag specified in the table */
    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category=GameplayTag)
    FString Tag;

    /** Text that describes this category - not all tags have categories */
    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category=GameplayTag)
    FText CategoryText;

    /** Constructors */
    FGameplayTagTableRow() { CategoryText = NSLOCTEXT("TAGCATEGORY", "TAGCATEGORYTESTING", "Category and Category"); }
    FGameplayTagTableRow(FGameplayTagTableRow const& Other);

    /** Assignment/Equality operators */
    FGameplayTagTableRow& operator=(FGameplayTagTableRow const& Other);
    bool operator==(FGameplayTagTableRow const& Other) const;
    bool operator!=(FGameplayTagTableRow const& Other) const;
};

我的頭文件 WeaponDataTable.h

#pragma once
#include "WeaponDataTable.generated.h"

USTRUCT()
struct FWeapon_Entry : public FTableRowBase
{
    GENERATED_BODY()
    
        /** Tag specified in the table */
        UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = GameplayTag)
        FString Tag;

        /** Text that describes this category - not all tags have categories */
        UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = GameplayTag)
            FText CategoryText;
    
        /** Text that describes this category - not all tags have categories */
        UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = GameplayTag)
            FText CategoryText1;

        /** Text that describes this category - not all tags have categories */
        UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = GameplayTag)
            FText CategoryText2;

        /** Text that describes this category - not all tags have categories */
        UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = GameplayTag)
            FText CategoryText3;
};


USTRUCT()
struct FWeapon_Client : public FTableRowBase
{
    GENERATED_BODY()

        /** Tag specified in the table */
        UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = GameplayTag)
        FString Tag;

    /** Text that describes this category - not all tags have categories */
    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = GameplayTag)
        FText CategoryText;
};

USTRUCT()
struct FWeapon_Spell_Entry : public FTableRowBase
{
    GENERATED_BODY()

        /** Tag specified in the table */
        UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = GameplayTag)
        FString Tag;

    /** Text that describes this category - not all tags have categories */
    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = GameplayTag)
        FText CategoryText;
};

USTRUCT()
struct FWeapon_Spell_Client : public FTableRowBase
{
    GENERATED_BODY()

        /** Tag specified in the table */
        UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = GameplayTag)
        FString Tag;

    /** Text that describes this category - not all tags have categories */
    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = GameplayTag)
        FText CategoryText;
};

我的對應(yīng)的cpp文件

#include "YourProjName.h" //你的項目頭文件
#include "WeaponDataTable.h"

最終效果

看，自定義表格成功

結(jié)論：

數(shù)據(jù)表在代碼層面也是結(jié)構(gòu)體，明白這一點，那么就不難理解上面代碼結(jié)構(gòu)體名和最終數(shù)據(jù)表可選類型的對應(yīng)關(guān)系。本帖將要推出

1. 用藍(lán)圖實現(xiàn)數(shù)據(jù)表
2. C++細(xì)說數(shù)據(jù)表內(nèi)容
