No Tienen La Capacidad De Generar Tablas O Plecas

Wikidot has three different way to do it. None of them quite satisfactory as you can see:

1. Usando solamente el comando de línea horizontal de Wikidot

I placed six ndashes like this ------ between my formulas, and got this:

$(A \supset \lnot B)$


$(B \supset \lnot A)$

Code is at its simplest, but the line is way too long.

2. Usando el markup para tablas simples

2.1 Solo

$(A \supset \lnot B)$
$(B \supset \lnot A)$

Can't remove vertical lines and horizontal lines at the top and bottom. Code is simple enough.

2.2 Combinado con la línea horizontal de Wikidot

$(A \supset \lnot B)$
--
$(B \supset \lnot A)$

Code is still quite simple, but the horizontal line is way too short.

3. Usando el markup de HTML para tablas avanzadas

3.1 Solo

1. $(A \supset \lnot B)$
2. $(B \supset \lnot A)$

Code is burdensome. Can't remove the horizontal line at the bottom nor two vertical lines on the sides of the conclusion.

3.2 Combinado con la línea horizontal de Wikidot

1. $(A \supset \lnot B)$

2. $(B \supset \lnot A)$

Code is burdensome, the unnecessary lines (vertical and at the bottom) are removed, but the intended horizontal line separating the conclusion is way too short and centered (instead of left aligned).

3.3 leiger modification:

1. $(A \supset \lnot B)$
2. $(B \supset \lnot A)$

leiger added:

Essentially, change this:
border: 1px solid black;
to this:
border-top: 1px solid black;

4. Last two formulas represented as a fraction.

By using the \frac{}{} command, we get this:

(1)
\begin{eqnarray} & 1. (A \supset \lnot B) \\ & \frac{ 2. (B \supset \lnot A) }{ 3. (A \supset \equiv \lnot B) } \end{eqnarray}
