MDMarkdown table rules
A valid table needs a header row, a separator row, and optional data rows.
The separator row such as |---|---|---| is only used to identify the header. It is skipped in preview data and CSV/XLSX export.
Text before or after the extracted pipe-table block is ignored during export.
