Hi Kyle,

Thanks for checking. Indeed ox-html export does not show that issue.

But the weekly cron (and even local) ox-hugo exports started showing this issue after the update to table.el table detection change that happened a few weeks ago.

I'll investigate why only ox-hugo is showing this issue.. I am simply calling the table.el related function from ox-html:

=====

(defun org-blackfriday-table (table contents info)
  "Transcode TABLE element into Blackfriday Markdown format.

CONTENTS is contents of the table.  INFO is a plist holding
contextual information."
  ;; (message "[ox-bf-table DBG] In contents: %s" contents)
  (if (eq (org-element-property :type table) 'table.el)
      ;; "table.el" table.  Convert it using appropriate tools.
      (let ((tbl (org-html-table--table.el-table table info)))
        (message "%S" table) ; just added this for debug
        (message "%S" tbl) ; just added this for debug

=====

and I am getting only partial table in the "tbl" variable
