LyX: Removing indentation from a table

Question

I want to make a table that has terms on the left side with .25\textwidth and descriptions on the right side with .75\textwidth Like

Name:                    asdjoia
Position:                astronaut
...:                     sadas

With the widths of the columns set, the table tends to be a bit on the right side of the paper though. I tried inserting a LaTeX argument for the table: @{}ll@{}, which indeed removes the indentation, but leaves me without the permanent width of the left side.

The source of the table looks like this:

\begin{tabular}{@{}ll@{}>{\raggedright}p{0.25\textwidth}>{\raggedright}p{0.75\textwidth}}
Name: & asdjoia\tabularnewline
Position: & astronaut\tabularnewline
...: & sadas\tabularnewline
\end{tabular}

And the related preamble code set to

\documentclass[danish]{article}
\setlength{\parindent}{0bp}
\providecommand{\tabularnewline}{\\}

Answer 1

You have removed the outer padding with @{} but you still have padding on the inner cell borders totalling 2\tabcolsep You may also have a paragraph indentation (depending on the code you didn't show) so

\noindent
\begin{tabular}{@{}ll@{}>{\raggedright}p{\dimexpr0.25\textwidth-\tabcolsep\relax}
                      >{\raggedright}p{\dimexpr0.75\textwidth-\tabcolsep\relax}}
