Question

I have a table, and it should be also border betwen C and D in the second row and border between 12 and 13. How to do that?

\documentclass{article}    
\usepackage[utf8]{inputenc}    
\usepackage[russian]{babel}   
\usepackage{multirow,tabularx}   
\begin{document}     

\begin{tabularx}{\textwidth}{ |X|X|X|X|с|с| }    
\hline    
\multirow{2}*{N} & \multirow{2}*{номер} & \multicolumn{2}{|c|}{Технические харектеристики} & \multicolumn{2}{|c|}{Поверка} \\   \cline{3-6}     
   &       & A & B & C  & D   \\ \hline     
 1 & 235  & ла & ба & 12  & 13   \\ \hline     
\end{tabularx}    
\end{document}    

Answer 1

Do you mean this?

\multicolumn is tricky with vertical rules (rather don't use them at all!)

\documentclass{article}    
\usepackage[utf8]{inputenc}    
\usepackage[russian]{babel}   
\usepackage{multirow,tabularx}   
\begin{document}     

\begin{tabularx}{\textwidth}{|X|X|X|X|c|c|}
\hline    
\multirow{2}*{N} & \multirow{2}*{номер} & \multicolumn{2}{c|}{Технические харектеристики} & \multicolumn{2}{c|}{Поверка} \\   \cline{3-6}     
   &       & A & B & C  & D   \\ \hline     
 1 & 235  & ла & ба & 12  & 13   \\ \hline     
\end{tabularx}    
\end{document}
