table column order is inconsistent with bbox.l coordinates

### Bug
When converting a pdf sometimes table the columns are out of order and the disagree with the tableCell's bbox.l ordering. When column headers are detected, the headers behave differently (not switched)

### Steps to reproduce
process this (https://assets.accessible-digital-documents.com/uploads/2017/01/sample-tables.pdf) pdf and examining markdown output and docling document tableItem for "Table 1", "Table 3", "Table 4"

pipline options:
do_picture_classification=False
do_picture_description=False
enable_remote_services=False
do_table_structure = True
ocr_options = doc_pipe_opts.OcrAutoOptions()
backend = doc_parse_v4.DoclingParseV4DocumentBackend
sample log output:

: #/tables/0: r[1]c[1]bbox.l (385.2) > r[1]c[2]bbox.l (90.0)
: Column header (TH) [90.0] | Column header (TH) [237.6] | Column header (TH) [385.2]
