Creating a table in Latex like this?

Question

I want to create a table like this using Latex

My code is, but I do not know how can make the second and third row in a table?

\begin {table}[ ]
\caption {The available bandwidth is divided into PRBs}          
\label{tab:The available bandwidth is divided into PRBs} 

\begin{center}
\begin{tabular}{| c | c |c |c |c |c |c |} 
\hline
 Bandwith & & & & & & \\ 
 (MHz) & 1.25 & 2.5 & 5.0 & 10.0 & 15.0& 20.0\\ 
 \hline 
 Subcarrier   & & & & & & \\   
 bandwidth (kHz)  & & & & & & \\  

 \hline
 Physical resource block   & & & & & & \\ 
 (PRBs) bandwidth (kHz)   & & & & & & \\  
 \hline 
 Number of available &   &   &   &   &   &  \\ 
 PRBs & 6 & 12 & 25 & 50 & 75 & 100\\ 
 \hline
 \end{tabular}
 \end{center}
 \end {table}

Do you have any ideas how to tex this layout? Thanks a lot

Answer 1

I don't know what exactly is your problem with typesetting this table in LaTeX, but I tried to reproduce all the features of your example. This code:

\documentclass{article}

\usepackage{array}
\newcolumntype{C}[1]{>{\centering\let\newline\\\arraybackslash\hspace{0pt}}m{#1}}
\renewcommand{\arraystretch}{2.0}

\begin{document}

\begin{tabular}{|>{\bfseries}C{5cm}|C{1cm}|C{1cm}|C{1cm}|C{1cm}|C{1cm}|C{1cm}|}
    \hline
    Bandwidth (MHz) & 1.25 & 2.5 & 5.0 & 10.0 & 15.0 & 20.0 \\
    \hline
    Subcarrier bandwidth (kHz) & \multicolumn{6}{c|}{15} \\
    \hline
    Physical resource block (PRB) bandwidth (kHz) & \multicolumn{6}{c|}{180} \\
    \hline
    Number of available PRBs & 6 & 12 & 25 & 50 & 75 & 100 \\
    \hline
\end{tabular}

\end{document}

compiles to this table:

Some notes on the commands I used:

• In the first column, you want to have central alignment, but at the same time automatically wrap in case the lines get too long. I follow this answer in defining a new column type C that gets a width (like in C{5cm}) but is centrally aligned. The same column type I use for the other columns, to have the numbers centered but with a fixed width.
• To extend a single cell over several columns, I use the \multicolumn command. It takes as a first argument the number of columns that should be spanned, as a second the cell types and vertical lines (here, I choose centered and a closing vertical line - the opening vertical line is produced by the first column), and as a third the cell content.
• To introduce a larger vertical spacing between the horizontal lines and the text in the cells, I redefine the arraystretch to factor 2.0, by \renewcommand{\arraystretch}{2.0}.
• Edit: I included the very good hint of JiyuuSensei: Using >{\bfseries} before the column type in the argument of tabular typesets all cells in the first column bold-faced, so I don't need to insert that manually in every row.

I hope that helps.
