Generating natural language statements to convey information from tabular data (i.e., Table-to-text) is a process with one input and a variety of valid outputs. This characteristic underscores the abilities to control the generation and produce a diverse set of outputs as two key assets. Thus, we propose a diversity enhancing scheme that builds upon an inherent property of the statements, namely, their logic-types, by using a type-controlled Table-to-text generation model. Employing automatic and manual tests, we prove its twofold advantage: users can effectively tune the generated statement type, and, by sampling different types, can obtain a diverse set of statements for a given table.
