关键就是对每列集合 生成笛卡尔积，感觉用python会比较方便的。写了个玩玩，仅供参考。

from itertools import product
import os

srcDir="E:/数据1"
dstDir="E:/数据2"

txtfiles=[f for f in os.listdir(srcDir) if f.endswith("txt") and os.path.isfile(f)]

for txt in txtfiles: 
    with open(txt,encoding="utf-8") as f:
        lines = [line.strip("\n").split("\t") for line in f]        
    columns = [[i for i in colHasEmpty if i] for colHasEmpty in zip(*lines)] 
    with open(os.path.join(dstDir,txt),"w",encoding="utf-8") as fw:
        for i in product(*columns):                
            print("".join(i),file=fw)
