The structure recognization of web table can be processed by two phases. first we need to filter out those non - genuine tables which is uesd not for relational information display but for creating any type of multiple - column layout to facilitate easy viewing. according to lots of observations to tables in web pages, the features are identified which best capture the characteristics of the genuine table compared to a non - genuine one, and then get the heuristic rules. based on these rules, algorithms are designed and implemented to evaluate the performance, as measured by ie evaluation metrics - recall, precision and f - measure. the result show that the performance of our algorithms is not less effectively than others
