谢谢加分！我把我的代码执行结果跟11楼对比了下，多显示了一行，代码修改了一下，就是没列出哪些列是一样的，只把这些列的内容打印出来了：

@echo off&setlocal enabledelayedexpansion
::将下面的[tab]改为实际的跳格键
set "tab=[tab]"
for /f "delims=" %%a in (a.txt) do (
  set "str=%%a"
  for /l %%b in (1 1 50) do (
    for /f "delims=%tab%" %%c in ("!str!") do set "_%%b=!_%%b!批%%c"&set "str=!str:*%tab%=!"
  )
)
echo,相同的列有：
for /f "tokens=1* delims==" %%h in ('set _') do (
  if "!%%i!"=="a" set "var=%%i"&echo,!var:批= !"
  set "%%i=!%%i!a"
)
pause>nul

  for /f "tokens=1-3 delims=_" %%x in ("!value!") do if not "%%y"=="" echo,第%%x %%y %%z列，内容为:!num:批= !
)
pause>nul

效率不高，见谅。
