如何自動對 [sideways] 表格中的行和列進行編號

Question

我正在嘗試排版橫向表格，自動對行進行編號並在列中進行子編號。我用了這個答案對行進行編號，但這只能讓我取得行標題編號。我希望各列具有與每行相對應的子編號（例如 1. 行標題 1a. 大約兩行...、1b....、1c....）。 MWE 保留了我的文件所需的一些格式，因此某些元素（例如橫向的表格）可能不是必需的。我的嘗試導致在行中繼續計數，而不是獲取子數字（例如，我在第一行中得到 1.2.3.4.，然後第二行從 5 開始。）我是 LaTeX 的新手，這是我的第一篇文章，如果這是顯而易見的或我在其他地方錯過了答案，我很抱歉。

像這樣？ （我\hskip只是為了減少字母數量。）

\documentclass[11pt,a4paper,openright,oneside]{book}

\usepackage{array}

\renewcommand{\arraystretch}{1.5}
\newcolumntype{L}[1]{>{\raggedright\let\newline\\\arraybackslash\hspace{0pt}}p{#1}}
\newcounter{rowcount}
\setcounter{rowcount}{0}
\newcounter{colcount}[rowcount]% auto reset
\renewcommand{\thecolcount}{\therowcount\alph{colcount}}
