[BUG] - {Lattice} SpreadsheetExtractionAlgorithm failing in capturing rows and cells

[GuroGuru]

Describe the bug
While extracting a PDF I realized some tables were getting split because a row was not captured, as if it was considered a blank line. On other tables, the last cell in the row was skipped.

Screenshots
The screenshots are not from the original PDF, but it will hopefully illustrate the problem.

Given a table with a schema similar to the image below:

I expected to capture the entire table at once:

However, once the 5th was skipped, I ended up with two distinct capture groups.

The other problem is that sometimes some cell are skipped. One example is the 1st capture, that have missing data at the 3 ending rows:

Sometimes the data skipping happens also when the table is not split.
