Answer 1

Can you make one for me?

Answer 2

It doesn't work here.
I once saw FFM make one but now he is gone.

Answer 3

An example:

\begin{array}{cc}
stuff & stuff\\
more stuff & more stuff\\
\hline
\end{array}{cc}

Answer 4

hmm, actually, you know how to check the commands, right? Want me to make several and let you see the structure of the environment?

Answer 5

\(\begin{array} ha & b & c \\ d & e & f \end{array}\)

How do i add lines?

Answer 6

I mean rows and columns.

Answer 7

\[\begin{array}{c|c|c}
a & b & c\\
a & b & c
\end{array}\]

Answer 8

Oh

\(\begin{array}{l | r} a & b \\ \hline c & d \end{array}\)

Answer 9

I see

Answer 10

Use \hline, that's all.

Answer 11

I was using matrix or align :P I once did that thing but I forgot it later

Answer 12

Where else can I use the array?

Answer 13

Array is vast. You can use it for almost anything.

Answer 14

How to make a table like this?

Answer 15

Well just a 1,2,3 table for example?

Answer 16

That requires a lot of patience. I can't remember how to make the headers and borders. But you essentially continuously use \hline and the column bars in the {} part.

Answer 17

What if I wanted to add a double line?

Answer 18

|| use that

Answer 19

double hline? use \hline, a \\ at the end, then \hline on the next row

Answer 20

\(\begin{array} {l | c || r} p & a & r & t & h \\ \hline \end{array}\)

Answer 21

I want something like a | b || c

Answer 22

Use
\[
\begin{array}{c|c|c}
a & & a\\
a & & a\\
\end{array}
\]

I can't quite recall another method.
