[Tex/LaTex] Adding vertical space between two \hline

spacingtables

How can I add vertical space between the double line in the example below? I tried to use \vspace, but that results in a Misplaced \noalign error.

\documentclass{article}

\begin{document}
    \begin{table}[h]
        \centering
        \begin{tabular}{|l|l|}
            \hline
            Test 1 & Blah \\
            \hline
            % <Add space here>
            \hline
            Test 2 & Blah \\
            \hline
        \end{tabular}
    \end{table}
\end{document}

The space is controlled by the parameter \doublerulesep which you can set at any point in the document

\setlength\doublerulesep{2cm}

Either in the preamble for the whole document or if just this table, inside the table environment alongside \centering and any other local declarations.

[Tex/LaTex] How to define the default vertical distance between nodes

I don't really get the question so I hope this is what you wanted. If you include a full document (such that we copy paste and see the problem on our systems) things are much more easier.

Here, you can change the default setting within a scope but your block style had a node distance which was resetting every time it is issued. I've made it 2mm such that we can see the difference easier.

\documentclass[tikz]{standalone}
\usetikzlibrary{arrows,shapes.geometric,positioning}

\begin{document}
\begin{tikzpicture}[decision/.style={diamond, draw, text width=4.5em, text badly centered, node distance=3.5cm, inner sep=0pt},
                    block/.style   ={rectangle, draw, text width=6em, text centered, rounded corners, minimum height=4em, minimum height=2em},
                    cloud/.style   ={draw, ellipse, minimum height=2em},
                    line/.style    ={draw,-latex'},
                    node distance = 1cm, 
                    auto]
    \node [block] (1st) {1st};
    \node [block, right= of 1st]  (2nd1) {2nd1};
\begin{scope}[node distance=2mm and 10mm]%Here we change it for everything inside this scope
    \node [block, above= of 2nd1] (2nd2) {2nd2};
    \node [block, below= of 2nd1] (2nd3) {2nd3};
    \node [block, right= of 2nd1] (3rd1) {3rd1};
    \node [block, above= of 3rd1] (3rd2) {3rd2};
    \node [block, above= of 3rd2] (3rd3) {3rd3};
\end{scope}
    \node [block, below= of 3rd1] (3rd4) {3rd4};
    \node [block, below= of 3rd4] (3rd5) {3rd5};

    \path [line] (1st) -- (2nd1);
    \path [line] (2nd1) -- (2nd2);
    \path [line] (2nd1) -- (2nd3);
    \path [line] (2nd2) -- (3rd3);
    \path [line] (2nd1) -- (3rd1);
    \path [line] (1st) -- (2nd1);
\end{tikzpicture}
\end{document}

[Tex/LaTex] how to make a line between two rows in table? (when no space between strings)

When building tables, the \hline command at the very beginning of a row: this means just after the \begin{tabular}{<column-spec>} line to come before the first row or immediately after \\ for the other rows.

(La)TeX commands are made up of the escape character (\), a series of letters up to the first non-letter or the escape character (\) followed by one non-letter. Following these rules, \hlineab is a separate command name from \hline: both are made up of the escape sequence followed by letters. Thus your system for building your table needs to include something after \hline to separate it from ab. The usual case would simply to be to include a space here

\\ \hline ab

If for some reason that is not possible, adding an empty group will also do the job

\\ \hline{}ab

(This latter trick is also used to stop TeX skipping spaces after a command: not relevant here but does show up for example when writing for example \LaTeX{} is a document preparation system: try without the braces and see the effect.)
