TBL-002 Empty cells

Overview

Validates that table cells are not empty. When columns is specified, only those columns are checked; otherwise every column is checked. Violations are reported as warning.

Why it matters

Adding a row to a requirements table with an empty Status, or forgetting to fill in the Description of an API entry, lowers the document’s completeness. These omissions are easy to miss in review, so detecting them mechanically is worthwhile.

Options

Field	Type	Required	Description
columns	string[]	—	Column names to validate. If omitted, all columns are checked
files	string	—	Glob of files this rule applies to

The rule works even with no options at all (every column of every table is checked).

Bad example

## Requirements

| ID     | Description           | Status |
| ------ | --------------------- | ------ |
| REQ-01 | User registration     | stable |
| REQ-02 | Password reset        |        |

With columns: ["Status"] (or no columns), the empty cell is detected.

docs/requirements.md
  line 5  warning  Empty cell in column "Status"  TBL-002

After fix

## Requirements

| ID     | Description           | Status |

| REQ-02 | Password reset        | review |
