CompTSRBench

CompTSRBench is a benchmark of 10,000 structurally complex synthetic tables for table structure recognition (image → HTML). Each table pairs a rendered image with its ground-truth HTML. The tables cover 25 canonical structural patterns (hierarchical headers, row and column spans, gridless regions and more) across application domains such as finance, science, education and healthcare.

Split	Tables
train	8,000
test	2,000

Every pattern appears in both splits, with at least 40 test tables per pattern.

Fields

Field	Type	Description
`id`	string	Table identifier
`split`	string	`train` or `test`
`pattern`	int	Canonical structural pattern (1–25)
`image`	image	Rendered table image
`html`	string	Ground-truth table HTML (minified, no styling); headers are marked with `<th>`

Structural statistics (all 10K tables)

81.4% contain column spans, 89.5% row spans, 58.4% multi-level headers
On average 17.3 merged cells per table

Usage

from datasets import load_dataset

ds = load_dataset("researchgroup542/Table_Dataset")
example = ds["test"][0]
example["image"]   # PIL image
example["html"]    # ground-truth HTML

Evaluation

We report TEDS, TEDS-Struct and the Triple Metric Score (TMS), a structure-first metric that checks each cell's position, header context and content in that order. See the paper for details.
