# [Tex/LaTex] How to write checkmark in latex

symbols

I want to put some checkmarks inside table cells.

I have put a cross sign using $\times$ but I really don't know how to write a checkmark in latex.

I used \usepackage{bbding} package and \checkmark but it doesnt work,

if it is \checkmark, it shows nothing

if it is \Checkmark, it shows a !

an example source code:
(there is an additional cls file IEEEtran.cls : mirrors.ctan.org/macros/latex/contrib/IEEEtran/IEEEtran.cls)

    \documentclass[conference]{IEEEtran}

\ifCLASSINFOpdf
\usepackage[pdftex]{graphicx}
\DeclareGraphicsExtensions{.pdf,.jpeg,.png,.eps}
\else
\usepackage[dvips]{graphicx}
\DeclareGraphicsExtensions{.eps}
\fi

\usepackage{lscape}
\usepackage{subfigure}
\usepackage{dingbat}
