Edit table cell style and spaces

Question

I'm struggling with tables in latex. I would like to have the following "word" effect:

but with the code:

\usepackage{booktabs}
\usepackage{colortbl}
\usepackage{xcolor}
\begin{center}
\begin{tabular}{c c c}
\textbf{INGESTION (Hz)} & \textbf{3 STREAMS} & \textbf{6 STREAMS}  \\ \toprule
\rowcolor{black!10}[0pt][0pt]50    & 1  & 1   \\
25    & 2  & 2 \\
\rowcolor{black!10}[0pt][0pt]15    & 3  & 3
\end{tabular}
\end{center}

I obtain this:

which is very ugly to me. Essentially I want to remove the space between the header and the first row, moreover I want remove the space between the cells of the rows (I used \arraystrech with terrible results). I'd like to add the extra header also.

You could also use tabularx. To center the column type X you use column type Y defined in Centering in tabularx and X columns.

MWE:

\documentclass{article}
\usepackage{booktabs}
%\usepackage{colortbl}
\usepackage[table]{xcolor}

\usepackage{tabularx}
\newcolumntype{Y}{>{\centering\arraybackslash}X}
\begin{document}
  \rowcolors{3}{black!10}{white}  
  \begin{tabularx}{0.76\textwidth}{Ycc}
  \textbf{INGESTION (Hz)} & \textbf{3 STREAMS} & \textbf{6 STREAMS}  \\ \toprule
50    & 1  & 1   \\
25    & 2  & 2 \\
15    & 3  & 3
  \end{tabularx}
\end{document}

The horizontal white strip is due to the padding added by the rules of booktabs. To remove it, you have to use \specialrule command, which gives you control on this padding for specific rules. The intercolumn white spaces are due to the optional [0pt]s in \rowcolor. Just suppress them. However a better solution, for alternating row colors is to use the \rowcolors command defined by xcolor with [table] option. Tthis option loads colortbl, so you don't have to do it.

Here's the result: \documentclass{article} \usepackage[utf8]{inputenc} \usepackage{booktabs} \usepackage[table, svgnames]{xcolor}

\begin{document}

\begin{center}
  \rowcolors{3}{Gainsboro}{white}
  \begin{tabular}{c c c}
    \multicolumn{3}{c}{\textbf{AVERAGE DATA LOSS (\%)}}\\
    \addlinespace
    \textbf{INGESTION (Hz)} & \textbf{3 STREAMS} & \textbf{6 STREAMS} \\
    \specialrule{\heavyrulewidth}{\aboverulesep}{0pt}
    50 & 1 & 1 \\
    25 & 2 & 2 \\
    15 & 3 & 3 \
  \end{tabular}
\end{center}

\end{document}

I find this the simple way. do you have any suggestions to add an extra header like the "word" style? – Akinn Nov 18 '17 at 01:11
@AndreaGiordano: Do you mean something like ‘Average Data Loss’ in your post? – Bernard Nov 18 '17 at 10:24
yes, I would like to add it – Akinn Nov 19 '17 at 19:07
@AndreaGiordano: The code has been updated, mylord! – Bernard Nov 19 '17 at 19:20

You can use a customized command to color the rows

\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{colortbl}
\usepackage{amsmath}
\usepackage{xcolor}
\usepackage{booktabs}

\newcommand{\ra}[1]{\renewcommand{\arraystretch}{#1}}
\colorlet{tablerowcolor}{black!10} % Table row separator colour = 10% gray
\newcommand{\rowcol}{\rowcolor{tablerowcolor}} %

\begin{document}

\begin{table}[!htpb]
\centering
\begin{tabular}{ccc}\toprule
\textbf{INGESTION(Hz)} & \textbf{3 STREAMS}& \textbf{6 STREAMS} \\ \toprule
\rowcol         50      & 1                     & 1             \\
                25      & 2                     & 2             \\
\rowcol         15      & 3                     & 3             \\ \bottomrule
\end{tabular}
\end{table}

\end{document}
