# Column Sizing

Set column widths that survive contact with your CSS

## What this does

You need columns to be certain widths and the numbers aren't landing the way you expect. This covers the size values a column carries, the APIs for reading positions and totals, and how those meet table, grid, or flex CSS. Reach for it when you expected auto or percentage widths, or when sizing and pinning disagree about the layout.

### Top 3 things it does for you

- Set a width and its minimum and maximum
- Read where a column starts and how much follows it
- Line sizing up with a table, grid, or flex layout

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.

This covers columnSizingFeature: the numeric size, minSize, and maxSize values, along with getSize, getStart, getAfter, and the total-size APIs, used within table, grid, or flex CSS.

Read it if you're carrying misconceptions about auto or percentage widths, or if sizing and pinning are producing a layout mismatch.

### Is Column Sizing safe to install?

AIR scanned this exact version of Column Sizing 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/column-sizing.
