# WildTableBench

[[Paper](https://arxiv.org/abs/2605.01018)] [[GitHub](https://github.com/hjzhe/WildTableBench)]

**WildTableBench** is a benchmark for evaluating multimodal foundation models on table understanding in the wild.

- **402 real-world table images** collected from diverse domains
- **928 questions** across 5 categories and 17 subtypes
- Covers numerical reasoning, verification, cell locating, structural understanding, and more

## Dataset Structure

```
WildTableBench/
├── metadata.csv       # 928 questions with labels
└── images/            # 402 table images (1.jpg … 402.jpg)
```

### `metadata.csv` columns

| Column | Description |
|---|---|
| `file_name` | Relative path to the image (e.g. `images/1.jpg`) |
| `image_id` | Image index (1–402) |
| `index` | Question index within the image (1, 2, …) |
| `uuid` | Unique question ID (e.g. `wtb_001_q1`) |
| `question` | Question text |
| `category` | Category ID (C1–C5) |
| `category_name` | Category name |
| `subtype_id` | Subtype ID (e.g. `C2-C`) |
| `subtype_name` | Subtype name |
| `ground_truth` | Ground truth answer |

## Question Categories

| ID | Name | Subtypes |
|---|---|---|
| C1 | Cell-Level | Transcription, Cell Locating, Semantic Lookup & Struct., Excel Formula |
| C2 | Numerical | Basic Numerical, Conditional Numerical, Multi-step Conditional, Ranking |
| C3 | Verification | Value Verification, Aggregate Verification, Conditional Verification |
| C4 | Hypothetical | Hypothetical Condition, Value Modification, Row Operation |
| C5 | Color | Color Identification, Color-based Counting, Color-based Reasoning |
