Markdown tables sent via the Feishu channel are displayed as raw source code because Feishu's post-type 'md' elements do not support table syntax. Convert markdown table content into Feishu Interactive Card JSON (schema 2.0) with native table components. Non-table markdown content is preserved as card markdown elements in the same message, with full markdown syntax support (headings, blockquotes, inline code, code blocks, etc.). Changes in gateway/platforms/feishu.py (~180 lines added): - _ParsedTable / _ContentSegment: data structures for parsed content - _parse_markdown_table(): parse pipe-delimited table text to headers/rows - _extract_tables_and_prose(): split mixed content into ordered segments, skipping tables inside fenced code blocks - _build_table_element(): convert parsed table to Feishu card table JSON - _build_table_card_payload(): assemble full interactive card (JSON 2.0) with markdown + table elements, with 100KB/5-table/50-column safeguards - _build_outbound_payload(): route table content to interactive cards instead of plain text - send(): add interactive -> text fallback on API failure Safety: - Tables inside fenced code blocks are not parsed (preserved as text) - Card JSON size limited to 100KB; falls back to text on overflow - Max 5 tables per card, max 50 columns per table (Feishu limits) - Full fallback chain: interactive card -> text on any send failure Co-Authored-By: wait4xx <X@alumni.nudt.edu.cn> Co-Authored-By: GLM 5.1
