只是将文本内容放入表中，没有替换：

@echo off&setlocal enabledelayedexpansion
for /f "delims=:" %%i in ('findstr /n .* a.txt') do set /a n=%%i-1
echo ┌─────────────────────────────────────┐
for /f "delims=" %%a in (a.txt) do (set str=%%a
    for /l %%k in (1 1 80) do (set "str=!str! "
        if "!str:~73!" equ " " echo │!str!│ 
)
    set /a m+=1
    if !m! leq %n% call :lp
)
echo └─────────────────────────────────────┘
pause>nul
:lp
echo ├─────────────────────────────────────┤
