Long table with top alignment with itemize

Question

Minimum Working Example

\documentclass{article}
\usepackage[hmargin=1cm,vmargin={1.25cm,1cm},
            footskip=2\baselineskip]{geometry}
\usepackage{tabularray}
\UseTblrLibrary{booktabs, varwidth}
\usepackage{enumitem}
\newlist{tabitemize}{itemize}{1}% <-- defined new list
\setlist[tabitemize]{nosep,     % <-- new list setup
                     leftmargin = *,
                     label = $\bullet$,
                     before = \begin{minipage}[t]{\linewidth}, % <---
                     after = \end{minipage}                    % <---
                     }
\usepackage{lipsum}
\begin{document}
\begin{longtblr}[

  label = {tab: },
                ]{
  colspec = {@{} Q[l, wd=6cm] Q[l, wd=8.5cm] @{}},
  row {1} = {font=\large\bfseries},
  rowhead = 1,
  measure = vbox,
                 }

\begin{tabitemize}
    \item \textbf{\Large test text left:}
    \lipsum[1-1]\footnote{test footnote left}
\end{tabitemize}
    &   \textbf{\Large test text right:}
        \lipsum[5-5]
        \begin{tabitemize}

Question

It can be seen that though the left and right columns are both aligned to the top, the level of their first lines is not matching. How to match them (text text left and right)?

Answer 1

You have two problems:

• table body is set as last foot. Remove command \lastfoot or move it after \endhead command
• itemize list insert some vertical space (\topsep) before lists, consequently in left column it is moved for this space down.

MWE below is suggestion for improving looks of your table. In it is resolved remedy of use \endfoot and for list used \enumitem package an defined new lists for use in tables.

\documentclass{article}
% Change the page layout if you need to
\usepackage[hmargin=1cm,vmargin={1.25cm,1cm},
            footskip=2\baselineskip]{geometry}
\usepackage{graphicx}
\usepackage{ragged2e}
\usepackage{array, booktabs, longtable, tabularx}
\renewcommand*{\arraystretch}{1.2}%... and increase the row height
\usepackage{enumitem}
\newlist{tabitemize}{itemize}{1}% <-- defined new list
\setlist[tabitemize]{nosep,     % <-- new list setup
                     leftmargin = *,
                     label = $\bullet$,
                     before = \begin{minipage}[t]{\linewidth}, % <---
                     after = \end{minipage}                    % <---
                     }
\usepackage{lipsum}
\begin{document}
\begin{longtable}{@{} >{\RaggedRight}p{6cm}>{\RaggedRight}p{8.5cm} @{}}
    \toprule
\textbf{{\large {Publications}}} & \textbf{{\large  {Publications}}} \
    \midrule
\endfirsthead
\endhead
    \begin{tabitemize}
        \item \textbf{\Large test text left:}
        \lipsum[1-1]
    \end{tabitemize}
    &   \textbf{\Large test text right:}
    \lipsum[5-5]
    \begin{tabitemize}
        \item \lipsum[1-1]
        \item \lipsum[1-1]
    \end{tabitemize}
    \
    \bottomrule
\end{longtable}

Addendum: You may consider to use tabularray package for your tables. Code for your long table using it, is:

\documentclass{article}
\usepackage[hmargin=1cm,vmargin={1.25cm,1cm},
            footskip=2\baselineskip]{geometry}
\usepackage{tabularray}
\UseTblrLibrary{booktabs, varwidth}
\usepackage{enumitem}
\newlist{tabitemize}{itemize}{1}% <-- defined new list
\setlist[tabitemize]{nosep,     % <-- new list setup
                     leftmargin = *,
                     label = $\bullet$,
                     before = \begin{minipage}[t]{\linewidth}, % <---
                     after = \end{minipage}                    % <---
                     }
\usepackage{lipsum}
\begin{document}
\begin{longtblr}[
caption = {My long table with caption},
  label = {tab: },
                ]{
  colspec = {@{} Q[l, wd=6cm] Q[l, wd=8.5cm] @{}},
  row {1} = {font=\large\bfseries},
  rowhead = 1,
  measure = vbox,
                 }
    \toprule
Publications    & Publications  \
    \midrule
\begin{tabitemize}
    \item \textbf{\Large test text left:}
    \lipsum[1-1]
\end{tabitemize}
    &   \textbf{\Large test text right:}
        \lipsum[5-5]
        \begin{tabitemize}
            \item \lipsum[1-1]
            \item \lipsum[1-1]
        \end{tabitemize}        \
    \bottomrule
\end{longtblr}
\end{document}

Result is similar (but a wee bit nicer) as before.
