awk使用基于先前匹配的第1列和第2列的值添加（追加/复制）缺少的列

输入文件示例格式：filea

    dataev 258 aaa val1 val3 val4 trim val 7999
    dataev 259 bbb 1 35 aa ff ggg dataev 259 bbb val1 val3 val4 set val 7999
    dataev 26 ccc 2 10 aa ff ggg dataev 26 ccc val1 val3 val4 set (val/x86) 7999
    dataev 26 ddd val1 val3 val4 trim val 7999
    dataev 262 qqqq 1 38 aa ff ggg dataev 262 qqqq val1 val3 val4 set (val/x86) 7999
    dataev 263 aaa 1 39 bb ff ggg dataev 263 aaa val1 val3 val4 set val 7999
    dataev 264 ppp val1 val3 val4 trim x64 7999
    dataev 264 888 1 40 cc ff ggg dataev 264 888 val1 val3 val4 set (val/x86) 7999
    dataev 265 ooo 1 41 bb ff ggg dataev 265 ooo val1 val3 val4 set val 7999

基于输入文件，应根据列$1和$2的匹配情况添加缺少的列（复制），并附加到缺少列和值的列 从“匹配的较长行/行”

输出：

不清楚，请您更清楚地说明填充值背后的逻辑是什么？val1 val2 val3表示在相关字段/列中没有任何用途的一些随机虚拟值，逻辑是填充“父”行的间隙，以便“更规范化”格式抱歉，但您必须更清楚地了解填充值的逻辑是什么？逻辑是填充“父”行的间隙，以便基于第1列和第2列使用“更规范化/对齐”的格式match@EdMorton谢谢你的意见
