Feishu Bitable

This handles Feishu's Bitable API, which is their multi-dimensional spreadsheet system. You get 27 field types with batch operations for creating, querying, and updating records across tables. The documentation is thorough about the common pitfalls: date fields need millisecond timestamps not seconds, person fields require array objects with open_id, and the default table comes with empty rows you'll want to delete before importing data. Batch operations cap at 500 records and writes must be serial with delays to avoid conflicts. The three reference docs cover field properties, record value formats, and complete examples. If you're building automation around Feishu tables or doing bulk data imports, this saves you from learning these quirks the hard way.
