Is there a way to create a grid here on PF that has square elements?

I ask because I'm yearning to make a post that will require a Cayley table.

Draw the table with it's cell entries by hand or using your own software and save as a .pdf or .jpg file . Upload to PF .

Code (Text):

begin{array}{c|c|c}
1.1&1.2&1.3\\
2.1&2.2&2.3\\
3.1&3.2&3.3
end{array}

between double \$-signs generates following table (backslash before begin and end)
$$\begin{array}{c|c|c} 1.1&1.2&1.3\\ 2.1&2.2&2.3\\ 3.1&3.2&3.3 \end{array}$$
