# Table

HTML table with styled headers, alternating rows, horizontal scroll

## Surfaces

web, google-meet-stage, email, pdf, google-apps-script-web, mcp-apps

## Fields

| Field | Type |
|---|---|
| caption | string (optional) |
| headers | list[string] |
| rows | list[list[string]] |
| col_widths | list[string] (optional, added 2026-07-24). One CSS width per column (e.g. ["46%","18%","18%","18%"]), switches to table-layout:fixed. Without it, a long label in one column can pull free space away from short single-glyph cells in the others. |
