# Cell Spanning

Merge cells across rows or columns without ragged output

## What this does

You want a grid where repeated values merge into one taller cell, or one row that stretches across several columns. This covers how those merges are declared and how covered cells are skipped so the row doesn't come out ragged. Reach for it when merges disappear after you sort or page, or when one cell swallows the whole table body.

### Top 3 things it does for you

- Merge repeated values down a column
- Span a cell across several columns in one row
- Fix spans that vanish after sorting or paging

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Cell Spanning

This covers merging adjacent body cells with cellSpanningFeature: opting a column into value-based rowSpan through spanRows, per-row colSpan through spanColumns, and the covered-cell convention where a span of zero means the cell is skipped.

Read it if you're building merged data grids, if spans disappear once you sort or paginate, if rows come out ragged, or if a single cell unexpectedly merges down the entire tbody.

## Questions

### Is Cell Spanning safe to install?

AIR scanned this exact version of Cell Spanning and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit d9cca007c015, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/cell-spanning.

### How do I install Cell Spanning?
