Below is an example, it seems rather complex for me. I can only make a table with dark lines, and don't know how to make the dark lines hollow ones.
Is there a way to embed such a fancy table in LaTeX?

Here is why every one says " get rid of vertical lines". Double lines everywhere add further to disaster.
\documentclass{article}
\usepackage{hhline}
\usepackage{caption}
\usepackage{booktabs}
\begin{document}
\begin{table}[htb]
\centering
\sffamily
\captionsetup{font={bf,sf},skip=0.5ex}
\caption*{Access Levels}
\begin{tabular}{||*{5}{l||}}
\hhline{|t:=:t:=:t:=:t:=:t:=:t|}
\bfseries Modifier & \bfseries Class & \bfseries Package & \bfseries Subclass & \bfseries World \\
\hhline{|:=::=::=::=::=:|}
\texttt{public} & Y & Y & Y & Y \\
\hhline{|:=::=::=::=::=:|}
\texttt{protected} & Y & Y & Y & N \\
\hhline{|:=::=::=::=::=:|}
\itshape no modifier & Y & Y & N & N \\
\hhline{|:=::=::=::=::=:|}
\texttt{private} & Y & N & N & N \\
\hhline{|b:=:b:=:b:=:b:=:b:=:b|}
\end{tabular}
\end{table}
\begin{table}[htb]
\centering
\sffamily
\captionsetup{font={bf,sf},skip=0.5ex}
\caption*{Access Levels}
\begin{tabular}{l*{4}{c}}
\toprule
\bfseries Modifier & \bfseries Class & \bfseries Package & \bfseries Subclass & \bfseries World \\
\midrule
\texttt{public} & Y & Y & Y & Y \\
\texttt{protected} & Y & Y & Y & N \\
\itshape no modifier & Y & Y & N & N \\
\texttt{private} & Y & N & N & N \\ \bottomrule
\end{tabular}
\end{table}
\end{document}

Decide yourself which one looks good. I like the second one.
As noted by touhami, adding \setlength\tabcolsep{1pt} produces a look more similar to the image in the question, but it is cramped IMO.
You may want to use colours to make Y and N conspicuous.
\documentclass{article}
\usepackage{hhline}
\usepackage{caption}
\usepackage{booktabs}
\usepackage[table]{xcolor}
\newcommand*{\myred}{\cellcolor{red!50}}
\newcommand*{\mygreen}{\cellcolor{green!50}}
\newcommand*{\mycolor}{\cellcolor{olive!40}}
\begin{document}
\begin{table}[htb]
\arrayrulecolor{white}
\doublerulesepcolor{gray!20}
\centering
\sffamily
\captionsetup{font={bf,sf},skip=0.5ex}
\caption*{Access Levels}
\begin{tabular}{||*{5}{c||}}
\hhline{|t:=:t:=:t:=:t:=:t:=:t|}
\rowcolor{blue!30}
\bfseries Modifier & \bfseries Class & \bfseries Package & \bfseries Subclass & \bfseries World \\ \hhline{|:=::=::=::=::=:|}
\mycolor\texttt{public} & \mygreen Y & \mygreen Y & \mygreen Y & \mygreen Y \\
\hhline{|:=::=::=::=::=:|}
\mycolor\texttt{protected} & \mygreen Y & \mygreen Y & \mygreen Y & \myred N \\
\hhline{|:=::=::=::=::=:|}
\mycolor\itshape no modifier & \mygreen Y & \mygreen Y & \myred N & \myred N \\
\hhline{|:=::=::=::=::=:|}
\mycolor\texttt{private} & \mygreen Y & \myred N & \myred N & \myred N \\
\hhline{|b:=:b:=:b:=:b:=:b:=:b|}
\end{tabular}
\end{table}
\end{document}

Yes and No rather than Y and N. You don't lose anything and you gain being more informative. Moreover, the words having different lengths are easier to distinguish.

I don't share your opinion that the table given in the question is nice. And I don't prefer the questions where OP only uses the tex.sx.com as "code generator" (i.e. to put the picture and to wait to the code). But if the LaTeX solution was presented here then I can show plain TeX solution (just for completeness).
The double lines table can be simply created by:
\input opmac
\input chelvet % Helvetica plus Courier
\def\tabstrut{\lower4pt\vbox to15pt{}} % more vertical space
\hfil {\bf Access Levels}
\smallskip
\hfil\frame{\table{|l||l||l||l||l|}{\crli
\bf Modifier & \bf Class & \bf Package & \bf Subclass & \bf World \crlli
\tt public & Y & Y & Y & Y \crlli
\tt protected & Y & Y & Y & N \crlli
\it no modifier & Y & Y & N & N \crlli
\tt private & Y & N & N & N \crli
}}
\bye
The result:

If you need the colored version, then we need to copy a few lines from OPmac-tricks page, because OPmac doesn't support colored cells by default.
\input opmac
\input chelvet % Helvetica plus Courier
\def\tabstrut{\lower4pt\vbox to15pt{}} % more vertical space
%%% The code from http://petr.olsak.net/opmac-tricks-e.html#cellcolor
\def\tabdeclareC{\futurelet\next\setcellcolor##\end\hfil\hfil}
\def\setcellcolor{\ifx\next\global \expandafter\setcellcolorC\else \expandafter\setcellcolorD\fi}
\def\setcellcolorC#1\fi#2\end#3#4{%
\setbox0=\hbox{{\tabiteml\localcolor#2\unskip\tabitemr}}%
{\localcolor#1\fi\tabstrut\leaders\vrule\hskip\wd0 \ifx#3\hfil plus1fil\fi}%
\kern-\wd0 \box0
\ifx#4\hfil {\kern-.2pt \localcolor#1\fi\leaders\vrule\hskip.2pt plus1fil}\fi
}
\def\setcellcolorD{\ifx\cellcolor\undefined \let\next=\setcellcolorN
\else \def\next{\expandafter\expandafter\expandafter\setcellcolorC\cellcolor}%
\fi \next
}
\def\setcellcolorN#1\end#2#3{#2\tabiteml{\localcolor#1\unskip}\tabitemr#3}
%%% The table:
\def\LightGreen{\setcmykcolor{.5 0 .5 0}}
\def\LightRed{\setcmykcolor{0 .5 .5 0}}
\def\LightBlue{\setcmykcolor{.3 .1 0 0}}
\hfil {\bf Access Levels}
\smallskip
{\tabskip=2pt \def\cskip{\noalign{\kern2pt}}
\let\cellcolor=\LightBlue \def\Y{\LightGreen Y} \def\N{\LightRed N}
\hfil\table{CCCCC}{
