vertical alignment of minipages in two columns in a longtable

Question

I began to learn latex and I use it to prepare a CV. I made good experiences by organizing my CV with a longtable, in order to define the widths and the alignments of the different text blocks.

In my example the longtable consists of only one row and two columns. Further more, each cell holds a minipage, themselves holding another tabular.

The minipages in both columns somehow influence each other. The more lines I am inserting in the right table, the farther down the left minipage is moving. Of course I want the minipages in both columns longtable to be fixed at the very top. This only happens when using tabular in the minipage. Using normal text, the minipages remain at the top.

Answer 1

You need to add the [t] positioning specifier not only to the minipage environments, but to both tabular environments as well.

%% preamble stuff omitted
\begin{longtable}{|A|B|}
    \fbox{
    \begin{minipage}[t][6cm]{0.14\paperwidth}
        \begin{tabular}[t]{|p{0.12\paperwidth}|} % <--- "[t]" is new
            Left Table\\
            left Table\\
        \end{tabular}
    \end{minipage}}
    &
    \fbox{
    \begin{minipage}[t][16cm]{0.69\paperwidth}
        \begin{tabular}[t]{|p{0.66\paperwidth}|} % <--- "[t]" is new
