bytefield inside tabular

Question

I wonder why it is not easily possible to put a bytefield enviroment into a tabular. This MWE

\documentclass[border=2mm]{standalone}
\usepackage{bytefield}
\begin{document}
\begin{tabular}{c}
    \begin{bytefield}{2}
         \bitheader{0-1} \\ \bitbox{1}{0} \bitbox{1}{2}
    \end{bytefield}
\end{tabular}
\end{document}

produces this pdflatex error:

! Extra }, or forgotten \endgroup.
<template> \unskip \hfil }
                          \hskip \tabcolsep \endtemplate 
l.5 \begin{bytefield}{2}

Because of the valid answer to this question, I fear that it's again some key codes which are mangled by bytefield. But I lack the ability to find the solution.

Edit (addendum):

While enclosing the bytefield in braces helps with the simple example, I noticed that trouble comes with more complicated use. Since the alignmend of the bytefield is a bit weird, I feel forced into using \raisebox so that the bytefield numbers no longer overlap with the previous line.

Freakingly, this works only with the first line. Consider this advanced example:

\documentclass[border=2mm]{standalone}
\usepackage{bytefield}
\begin{document}
\begin{tabular}{l}\hline
    \raisebox{-1ex}[5ex][1.5ex]{
        {\begin{bytefield}[endianness=big,bitwidth=5em]{1}
        \bitheader{0} \\ \bitbox{1}{uint8}
        \end{bytefield}}}
    \\ \hline
    \raisebox{-1ex}{
        {\begin{bytefield}[endianness=little,bitwidth=5em]{2}
        \bitheader{0,1} \\ \bitbox{1}{MSB} & \bitbox{1}{LSB}
        \end{bytefield}}}
\end{tabular}

which produces the error

! Extra alignment tab has been changed to \cr.
<template> \endtemplate 
l.13    \end{bytefield}}}

If the second \raisebox is removed, the first line's layout is correct, the second is not:

Answer 1

You just need to brace the bytefield environment:

\documentclass[border=2mm]{standalone}
\usepackage{bytefield}

\begin{document}

\begin{tabular}{c}
  {\begin{bytefield}{2}
   \bitheader{0-1} \\ \bitbox{1}{0} \bitbox{1}{2}
   \end{bytefield}}
\end{tabular}

\end{document}

Addendum

There is no misalignment if you properly protect the end-of-line; if you have bytefield inside \raisebox, there's no need of the additional braces, already provided by \raisebox (implicitly), but they do no harm.

\documentclass[border=2mm]{standalone}
\usepackage{bytefield}

\begin{document}
\begin{tabular}{l}\hline
    \raisebox{-1ex}[5ex][1.5ex]{% <---- HERE
        \begin{bytefield}[endianness=big,bitwidth=5em]{1}
        \bitheader{0} \\ \bitbox{1}{uint8}
        \end{bytefield}}
    \\ \hline
    \raisebox{-1ex}[5ex][1.5ex]{% <---- HERE
        \begin{bytefield}[endianness=little,bitwidth=5em]{2}
        \bitheader{0,1} \\ \bitbox{1}{MSB} \bitbox{1}{LSB}
        \end{bytefield}}
\end{tabular}
\end{document}
