# Rename a table, change its Studio icon or primary field

`PATCH https://studio.grid82.app/v1/apps/{appId}/tables/{tableId}`

The id never changes: it is the column name and what every rule and page points at.

The name is what people read. The icon is a Lucide name used only in the Studio; null restores the default table icon.

Requires the `schema:write` scope. Operation `tables.update`. MCP tool `tables_update`. CLI: `grid82 tables update` (`npx grid82`).
