Here GitHubTableMarkerBlock#fillCells nodes for cells and separators are created. And a node for a cell is created even if its length is zero.
And then here TreeBuilder#constructEvents events are created, and for nodes with zero lengths, only one event is created (and not two as elsewhere). And then after sorting, these events are strangely located. Such a cell appears to be between the opening and closing of the separator.
Therefore, I think that it is necessary to correct how these events are compared, specifically in the case of an empty event.
