Before revision:  The fused features of both are used to characterize each table grid . We find that by adding additional semantic features to each grid, the ambiguity problem of the table structure from the visual perspective can be solved to a certain extent and achieve higher precision .
After revision:  The fused features of both are used to characterize each table grid from both vision and language modalities. Moreover, we achieve a higher precision in our experiments through adding additional semantic features .
