I am trying to fit a long table in multiple landscape pages by using longtable, and I would like it to break between columns (here I reduced its number of rows for simplicity):

\documentclass[12pt]{scrreprt}
\usepackage{longtable}
\usepackage{pdflscape}
\usepackage{dcolumn}

\begin{landscape}
        \tiny
    \begin{longtable}{@{\extracolsep{0pt}} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2} D{.}{.}{-2}}

I read multiple threads in this and other blogs, but can't find a solution. I am not using a figure or table environment, and I run the code many times (I read that using multicolumn it may take longer to produce the correct layout). Can anyone help me? Is maybe \hline confusing LaTeX?

  • longtable breaks between rows if you had lots lf lines it would break, it does not break between columns.

  • Hi @DavidCarlisle, thank you for your comment. I modified my question to make it clearer: I would like it to break between columns: isn't it possible?

  • Vera there is no particularly good automatic column breaker, certainly longtable won't help at all.

longtable not relevant here unless you have more rows in the table.

the table is simply too wide, you can make it narrower, for example:
