我正在使用Tableau Public从＆＃39; |＆＃39;中读取数据。分隔的文本文件。目标是确定每个玩家受到的伤害与收到的伤害程度。目前，数据仅显示每个攻击者的行数。如何更改数据以便为每个播放器看到一行？
示例来源：
Attacker Name | Attacker Nation | Defender Name | Defender Nation | Attacking Damage | Defending Damage
Bob | Builder | Felix | Fixer | 100 | 120
Bob | Builder | Ralph | Wrecker | 150 | 75
Felix | Fixer | Ralph | Wrecker | 125 | 150
期望的输出：
Name | Nation | Opponent Name | Opponent Nation | Damage Dealt | Damage Received
Bob | Builder | Felix | Fixer | 100 | 120
Bob | Builder | Ralph | Wrecker | 150 | 75
Felix | Fixer | Bob | Builder | 120 | 100
Felix | Fixer | Ralph | Wrecker | 125 | 150
Ralph | Wrecker | Bob | Builder | 75 | 150
Ralph | Wrecker | Felix | Fixer | 150 | 125
