+
+## Append Mode (Table-based updates)
+
+When using `-append` mode, the tool will maintain a single comment with a table of custom columns. This is useful for CI/CD pipelines that need to consolidate multiple results in one comment.
+
+**Example:**
+```bash
+# First package
+./pr-comments -token="$GITHUB_TOKEN" -pr="$PR_NUMBER" \
+  -owner="owner" -repo="repo" \
+  -body="<!-- package-publish-status -->
+## :package: Package Publishing Status
+> Packages published from this PR" \
+  -body-includes="<!-- package-publish-status -->" \
+  -append \
+  -row-id="@myorg/package-a" \
+  -columns="Package,Status,Version,Time" \
+  -values="@myorg/package-a,:white_check_mark: success,\`@myorg/package-a@1.0.0-alpha.1\`,12:34:56"
+
+# Second package
+./pr-comments -token="$GITHUB_TOKEN" -pr="$PR_NUMBER" \
+  -owner="owner" -repo="repo" \
+  -body="<!-- package-publish-status -->
+## :package: Package Publishing Status
+> Packages published from this PR" \
+  -body-includes="<!-- package-publish-status -->" \
+  -append \
+  -row-id="@myorg/package-b" \
+  -columns="Package,Status,Version,Time" \
+  -values="@myorg/package-b,:x: failure,-,12:35:10"
+```
+
+This will create or update a comment that looks like:
+
+```markdown
+<!-- package-publish-status -->
+## 📦 Package Publishing Status
+> Packages published from this PR
+
+| Package | Status | Version | Time |
+|---------|--------|---------|------|
+| @myorg/package-a | ✅ success | `@myorg/package-a@1.0.0-alpha.1` | 12:34:56 |
+| @myorg/package-b | ❌ failure | - | 12:35:10 |
+```
