[geoHeil]

Given the files of #806 (comment)

see #806 (comment) for the files

how can the table detection be streamlined so

396 |                 |
397 | 8173.3 >16666.7 |

this error does not occur?

In fact, here is a 2nd example - here the columns are detected in a flipped way for both easyocr and rapidocr and rapidocr with the EN model.
