	abstract = {It has been argued for some time that tabular representations of formal specifications can help in writing them, in understanding them, and in checking them. Recently it has been suggested that tabular representations also help in breaking down large verification and refinement conditions into a number of smaller ones.

The article [32] developed the theory, but the real proof in terms of an implementation is not provided. This project is about formalizing tables in a theorem prover, Simplify, defining theorems of [32] in terms of functions written in the OCaml programming language, and conducting some case studies in verifying and refining realistic problems.

A parser is designed to ease our job of inputting expressions. Pretty-print is also provided: all predicates and tables of the examples in our thesis are automatically generated.

Our first example is a control system, a luxury sedan car seat. This example gives us an overall impression on how to prove correctness from tabular specification. The second example specifies a visitor information system. The design features of this example involve modeling properties and operations on sets, relations and functions by building self-defined axioms. The third example illustrates another control system, an elevator. Theorems of algorithmic refinements, stepwise data refinements, and the combination of algorithmic abstraction and data abstraction are applied correspondingly to different operations.},
