How to make the column separator to touch the frame rule?

Question

I need ot adjust the column seperator line somehow to touch the frame lines which gives a look like table environment.

I was somehow not interested in using tabular environment for this purpose since, the enumeration does not go well with that.(For example, the item numbers are coming in the middle of the table(vertically), not from the top left corner of the table.

How to achieve this?

So far, I have tried using framed environment to get the borders and adjusted the rule command to split the frame environment vertically. Now horizontally also I need to split which I am not able to achieve.

MWE:

\documentclass[a4paper,11pt]{article}
\oddsidemargin 0in \evensidemargin 0in \topmargin 0in \textheight 9.2in  \textwidth 6.5in
\usepackage{enumitem, lipsum,xcolor}
\usepackage{framed}
\newlength{\framedline}
\setlength{\framedline}{\textwidth plus 18pt}
\let\oldrule\rule
\renewcommand{\rule}[2]{
   \hspace*{-36.7pt}\oldrule{\framedline}{0.4pt}\newline
}

\usepackage{multicol}
\setlength{\columnseprule}{1pt}

One approach using tcolorbox:

\documentclass[a4paper]{article}
\usepackage[margin=2cm]{geometry}
\usepackage{lipsum}
\usepackage{ulem}
\usepackage[shortlabels]{enumitem} 
\usepackage[most]{tcolorbox}
\tcbuselibrary{breakable}

\newtcolorbox{rowtable}[1][]{%
breakable,enhanced,nobeforeafter,colback=white, 
boxsep=1em, after skip=0pt,before skip=-1pt,
arc=0mm,boxrule=1pt, segmentation style={solid,}}

\newtcolorbox{rowcell}[1][]{%
