im +messages-send --markdown: table syntax and blank lines are silently dropped

[Astro-Han]

Environment

• OS: macOS 26.3.1 arm64
• lark-cli version: v1.0.2
• Shell: zsh

Description

When sending messages with --markdown, two formatting issues occur:

1. Markdown tables are completely lost — | col | col | syntax produces no output at all, the table content disappears silently
2. Blank lines are collapsed — double newlines \n\n between paragraphs are compressed to single newlines, removing paragraph spacing

Steps to Reproduce

lark-cli im +messages-send --as bot --chat-id "oc_xxx" --markdown '**Test**

| Item | Status |
|------|--------|
| Table | Testing |

Paragraph 1

Paragraph 2 (should have blank line above)'

Expected output in Feishu

**Test**

| Item   | Status  |
|--------|---------|
| Table  | Testing |

Paragraph 1

Paragraph 2 (should have blank line above)

Actual output in Feishu

Test
Paragraph 1
Paragraph 2 (should have blank line above)

• Table is completely missing
• Bold renders correctly
• All blank lines between paragraphs are gone

Impact

This makes --markdown unreliable for any structured data output. Users must fall back to --text (which preserves blank lines but has no formatting) or manually format with lists instead of tables.

Current workaround

• Use bullet lists instead of tables: - Item: Status
• Use --text when paragraph spacing matters
• Use --markdown with --- (horizontal rule) as a visual separator instead of relying on blank lines

Thanks for reporting this.

We’ve already fixed the blank-line issue, and the fix will be included in an upcoming release very soon. We’ll mark this as a bug and keep the owner assigned until the release is out.

For table syntax, support depends on Feishu exposing the corresponding platform capability. We’re continuing to track that dependency, and we’ll update the implementation as soon as the capability becomes available.
