Self-explanatory title. I'm new to LaTeX and this table looks pretty ugly.

enter image description here

\documentclass[letterpaper]{article}
\special{papersize=8.5in,11in}
\usepackage{indentfirst}
\usepackage{mathtools}
\usepackage{amssymb}
\usepackage{amsmath}

\usepackage{gensymb}
\usepackage[margin=1in]{geometry}
\setlength{\parskip}{1em}

\begin{document}

\begin{table}
\centering
\begin{tabular}{|c|ccccc|} 
\hline
     &  $0$ & $\frac{\pi}{6}$      & $\frac{\pi}{4}$      & $\frac{\pi}{6}$      
& $\frac{\pi}{2}$  \\ 
\hline
$\sin x$ & $0$  & $\frac{1}{2}$        & $\frac{\sqrt{2}}{2}$ & 
$\frac{\sqrt{3}}{2}$ & $1$  \\
$\cos x$ & $1$  & $\frac{\sqrt{3}}{2}$ & $\frac{\sqrt{2}}{2}$ & $\frac{1}{2}$        & $0$  \\
$\tan x$ & $0$  & $\frac{\sqrt{3}}{3}$ & $1$                  & $\sqrt{3}$           &   \\
\hline
\end{tabular}
\end{table}

\end{document}

Thank you.

    Welcome to TeX.SE! How about \renewcommand{\arraystretch}{1.57}? I'd also like to encourage you to be a bit more specific, i.e. to tell us what you wish to achieve. Otherwise there is a danger that this question could be closed as "primarly opinion based". – user121799 Sep 26 '18 at 1:44

    The booktabs package (and documentation) has some strongly held opinions about making tables pretty. #1 is no vertical lines. But I do agree with marmot that it's not clear what you want to achieve. – Teepeemm Sep 26 '18 at 1:48

    It would also be helpful (for us casual readers) to include an image of the "ugly" table. – MrWhite Sep 26 '18 at 16:12
  • Typo: the second $\frac{\pi}{6}$ in the heading should be $\frac{\pi}{3}$. So far, all the answers have reproduced this error faithfully! – TonyK Sep 26 '18 at 18:44
  • This might be tangential, but looking at the answers I have this great urge to nicely ask for filling the gap in place for tan(pi/2). It almost looks like an erroneous omission. – luk32 Sep 26 '18 at 23:24

I'd keep it as simple as possible.

\documentclass{article}
\usepackage{amsmath}
\usepackage{mathtools}
\usepackage{amssymb}

\usepackage{booktabs}
\usepackage{array}
\usepackage{caption} % optional

\begin{document}

\begin{table}

\centering

\caption{Table of trigonometric functions for common angles}

$
\setlength{\arraycolsep}{12pt} % for this particular table
\begin{array}{@{} l *{5}{>{\displaystyle}c} @{}}
\toprule
  &  0 & \frac{\pi}{6}      & \frac{\pi}{4}      & \frac{\pi}{6} & \frac{\pi}{2}  \\ 
\midrule
\sin x
  & 0  & \frac{1}{2}        & \frac{\sqrt{2}}{2} & \frac{\sqrt{3}}{2} & 1  \\
\addlinespace
\cos x
  & 1  & \frac{\sqrt{3}}{2} & \frac{\sqrt{2}}{2} & \frac{1}{2}        & 0  \\
\addlinespace
\tan x
  & 0  & \frac{\sqrt{3}}{3} & 1                  & \sqrt{3}           &   \\
\bottomrule
\end{array}
$

\end{table}

\end{document}

I use array to simplify the input (no $ necessary except around the array). With \addlinespace we can easily separate the lines. With a larger value of \arraycolsep we better separate the columns for ease of reading in this particular case.

my primary concern is to simplify your code. other is opinion based ...

  • instead tabular i would use array and than remove all $ in table code
  • for more vertical space i would employ the makecell package, i.e. use its macro \gapedcells:
  • note: mathtools load amsmath, so there is no need to load it again (loading packages more than once is not always innocuous...)

    \documentclass[letterpaper]{article}
    \usepackage[margin=1in]{geometry}
    \usepackage{indentfirst}
    \usepackage{mathtools}
    \usepackage{amssymb}
    %\usepackage{gensymb}   % <--- do you really need?
    \usepackage{makecell}   % <--- new
    
    \setlength{\parskip}{1em}
    
    \begin{document}
    
    \[\setcellgapes{3pt}
      \makegapedcells
    \begin{array}{c|ccccc}
            & 0 & \frac{\pi}{6}      & \frac{\pi}{4}      & \frac{\pi}{6}      & \frac{\pi}{2} \\
        \hline
    \sin x  & 0 & \frac{1}{2}        & \frac{\sqrt{2}}{2} & \frac{\sqrt{3}}{2} & 1      \\
    \cos x  & 1 & \frac{\sqrt{3}}{2} & \frac{\sqrt{2}}{2} & \frac{1}{2}        & 0      \\
    \tan x  & 0 & \frac{\sqrt{3}}{3} & 1                  & \sqrt{3}           & \infty \\
    \end{array}
    \]
    
    \end{document}

  • This is by far the best looking table IMHO. – TonyK Sep 26 '18 at 18:45

  1. Use \toprule and \bottomrule from booktabs at the beginning and end of your table
  2. Remove rules among columns and rows except the first one
  3. Use tabularx with type X column instead of tabular (it is better since you force columns with similar contents to be of equal size, at least in my opinion)
  4. Stretch your array \renewcommand{\arraystretch}{1.5}
  5. Use 'tab' to indent nested contents (this is to make debugging and revisions easier)

A workaround in tabu, an extension of tabularx; the most important thing to better presentations for fractions in math is to preserve the size of the numbers for this reason you must use \dfrac instead \frac; in the MWE some colors and rules modifications with tabu.

In my opinion, cals, the packages bm and cmbright and some light colours, are improvements:

\documentclass[a4paper, 11pt]{article}
\usepackage{bm, cmbright, cals}
\usepackage[dvipsnames]{xcolor} 
\renewcommand{\sfdefault}{cmbr}
%\everymath{\displaystyle}                                  % Nicest without displaystyle?
