# MD056 - Keep table column count consistent
## What this rule does
Ensures every row in a table has the same number of columns as the header row, preventing broken or misaligned tables.
## Why this matters
- **Proper rendering**: Tables with inconsistent columns may display incorrectly or break entirely
- **Data integrity**: Missing or extra columns can indicate missing or misplaced data
- **Professional appearance**: Well-formed tables look organized and trustworthy
- **Parser compatibility**: Many Markdown parsers require consistent column counts
## Examples
### ✅ Correct
```markdown
| Alice | Sales | 5 |
| Bob | Marketing | 3 |
| Charlie | IT | 7 |
```
### ✅ Correct (with empty cells)
```markdown
| Alice | Sales | 5 |
| Bob | | 3 |
| Charlie | IT | |
```
### ❌ Incorrect
```markdown
| Alice | Sales | 5 |
| Bob | Marketing | | Extra data |
| Charlie | IT |
```
### 🔧 Fixed
```markdown
| Alice | Sales | 5 |
| Bob | Marketing | |
| Charlie | IT | |
```
