Updates an existing custom table's metadata and, optionally, replaces its full set of columns. Requires the acting user to be an owner-admin. The tab value is the target tab's page ID; use Custom Fields > List Custom Fields (list-custom-fields) to find the pageId of an existing field on the desired tab — changing tab moves the table to that page. Any id in the request body is ignored; the table edited is always the one identified by the path. Omitted optional fields reset rather than persist: leaving out allowEdits resets it to true, and leaving out sortOrderDirection resets it to desc. Omitting columns leaves existing columns unchanged; including columns replaces the entire column set, deleting any existing column whose id is not present in the array — include a column's id to update it in place, or omit id to add a new column. To add a single column without resending the rest, use Create Custom Table Field (create-public-custom-table-field) instead; to delete a single column without resending the rest, use Delete Custom Table Field (delete-public-custom-table-field) instead; to reorder columns without resending field definitions, use Reorder Custom Table Fields (reorder-public-custom-table-fields) instead. A request that changes nothing returns the table unchanged rather than an error.
