Hello. The easiest (and nicest) way to do this is using the tikz
package: in the preamble put
\usepackage{tikz}
and then, wherever you want the tableau, put in a TeX box the following:
\def\land{\wedge}
\def\lor{\vee}
\def\limp{\to}
\begin{tikzpicture}
\node {$\{\neg ((p \lor (p \land q)) \limp p)\}$}
child {node {$\{p \lor (p \land q), \neg p\}$}
child {node {$\{p\}$}}
child {node {$\{p \land q\}$}
child {node {$\{p,q\}$}}}};
\end{tikzpicture}
Note that the structure of the tree depends on the grouping braces {
... }.

Dear LyX Colleagues,
I'm trying to create tableau proofs, which are branching columns
of text, as illustrated in the attachment. Examples can also be
found in Melvin Fitting and Richard Mendelsohn, /First-Order Modal
Logic/, Kluwer, 1998. Any help will be appreciated.
