Detect Tables without Visible Cell Separators

Tables with visible grid lines (gridded tables) in an original page can usually be detected successfully by the auto-zoning method. However, tables without visible cell separators in the original are harder to identify as tables, because they could alternately be word lists or data arranged in columns. The recognition engine offers an algorithm for detecting such non-gridded tables more confidently. This feature can only be used in conjunction with an auto-zoning step. The algorithm to detect non-gridded tables is based on the result of character recognition. This algorithm will run only if all the following conditions are met:

The zone list was created through auto-zoning
There were no changes in the zone list (no zones were inserted or deleted)
None of the zones in zone list were updated by modifying the zone coordinates
The feature is enabled through the ImGearRecRecognitionSettings.DecompDetectNongriddedTablesEnabled Property
