I asked about which logic because that determines which operators you will need (I've only given you a few in my examples), but also because for some logics the tableaux are not trees but directed acyclic graphs, (e.g., in temporal logics). This of course has a big impact on how to draw the tableau

Ernesto, I'm writing a paper using LyX, and I need to insert several specific tableaus into it. Using your numbers: 1) I do not want to add just *any* tableau example. 2) I do want to add several specific tableaus containing particular formulas. Probably just five or six such tableaus, each of

Didn't my last suggestions help? I am still unsure about whether you want to 1) add *any* tableau example, 2) add a specific tableau (i.e., a particular example that you have in mind with particular formulas), or 3) be able to make your own tableaux. If it is 1 or 2, which logic? Please clarify.

Scott, Yes, what a good idea. Here are two examples of what I've been able to do so far. In both of the following examples I've copied the code directly out of the TeX Code box which I got from the Insert menu on the LyX toolbar. *First example*: It would be perfect if it did not have those ve
