Mesa de ancho completo con varias columnas.

Question

Tengo un problema al crear una tabla de ancho completo con varias columnas.

El código es:

\documentclass[]{article}
\usepackage{longtable,booktabs}
\usepackage{geometry}
 \geometry{
 a4paper,
 left=20mm,
 right=20mm,
 top=20mm,
 bottom=20mm
 }

\usepackage{ltablex}
\usepackage{calc}
\usepackage[dvipsnames,table]{xcolor}
\usepackage{lipsum}

\definecolor{header-color}{HTML}{C0C0C0}
\definecolor{color-reserved}{HTML}{E0E0E0}
\definecolor{color1}{HTML}{F0F0F0}
\definecolor{color2}{HTML}{FFFFFF}

\begin{document}

\begin{tabularx}{\linewidth}%
   {% col 1
   |p{\widthof{Bit(s)}}|%
   % col 2
   p{\widthof{FIELD1\_NAME}}|%
   % col 3
   p{\widthof{Permissions}}|%
   % col 4
   p{\widthof{Reset Value}}|%
   % col 5
   X|
   }

    \hline
\rowcolor{header-color}
    \rowcolor{header-color}{\bf Bit(s)} & {\bf Field Name} & {\bf Permissions} & {\bf Reset Value} & {\bf Attributes} \\
    \hline
    \hline
    \endfirsthead
    \hline
    \rowcolor{header-color}{\bf Bit(s)} & {\bf Field Name} & {\bf Permissions} & {\bf Reset Value} & {\bf Attributes} \\
    \hline
    \hline
    \endhead

\rowcolor{color-reserved}0        & Reserved   & --          & --          & \\\hline  
\rowcolor{color2}
1         & FIELD1\_NAME & RW & 0x0 & \\\hline 
\rowcolor{color2}
             & \multicolumn{4}{p{\hsize}|}{
\lipsum[1-2]

} \\\hline 
\end{tabularx}

\end{document}

Lamentablemente no es lo que esperaba.

1. El ancho de la columna "Permiso" no es lo suficientemente ancho
2. Hay un espacio adicional en el lado derecho que no debería estar ahí.

Mis expectativas eran que Xestiraría la columna derecha al ancho del texto (como se define en la configuración de la tabla).

Tengo la intención de crear esta tabla a partir del script y no puedo establecer los tamaños de las columnas como constantes.

Dos posibilidades con columnas fijas con ptipo o lcolumnas de tipo:

\documentclass[]{article}
\usepackage{longtable,booktabs}
\usepackage{geometry}
 \geometry{
 a4paper,
 left=20mm,
 right=20mm,
 top=20mm,
 bottom=20mm
 }

\usepackage{ltablex}
\usepackage{calc}
\usepackage[dvipsnames,table]{xcolor}
\usepackage{lipsum}

\definecolor{header-color}{HTML}{C0C0C0}
\definecolor{color-reserved}{HTML}{E0E0E0}
\definecolor{color1}{HTML}{F0F0F0}
\definecolor{color2}{HTML}{FFFFFF}
\usepackage{makecell}
\renewcommand{\theadfont}{\normalsize\bfseries}
\begin{document}

\begin{tabularx}{\linewidth}%
   {% col 1
   |p{\widthof{\bfseries Bit(s)}}|%
   % col 2
   p{\widthof{FIELD1\_NAME}}|%
   % col 3
   p{\widthof{\bfseries Permissions}}|%
   % col 4
   p{\widthof{\bfseries Reset Value}}|%
   % col 5
   X|
   }

    \hline
    \rowcolor{header-color}{\bfseries Bit(s)} & {\bfseries Field Name} & {\bfseries Permissions} & {\bfseries Reset Value} & {\bfseries Attributes} \\

\rowcolor{color2}
             & \multicolumn{4}{p{\textwidth-4\tabcolsep-3\arrayrulewidth-\widthof{\bfseries Bit(s)}}|}{
\lipsum[1-2]

\end{tabularx}


\begin{tabularx}{\linewidth}%
