hermes - 💡(How to fix) Fix [Feature Request] Support Slack Block Kit table rendering for markdown tables [1 pull requests]

Problem

When Hermes Agent sends messages to Slack with markdown table syntax (e.g. | col1 | col2 |), the tables are not rendered as proper Slack tables — the pipe characters and formatting are displayed as plain text.

What works

Other agents (e.g. OpenClaw) successfully render markdown tables in Slack by converting them to Slack's native Block Kit section + mrkdwn blocks before sending via chat.postMessage.

Suggested solution

Add support for converting markdown tables (lines starting with | and containing | separators) into Slack Block Kit blocks. This would allow messages like:

| Header 1 | Header 2 |
| -------- | -------- |
| Cell 1   | Cell 2   |
| Cell 3   | Cell 4   |

...to render as an actual Slack table instead of raw markdown text.

Notes

• OpenClaw handles this via a markdownToIR() → buildSlackPresentationBlocks() pipeline
• The Slack API supports table rendering via Block Kit — it does support this natively
• A possible fallback for complex tables is rendering them inside a section block with mrkdwn: true as monospace-formatted text
