Sorry, never got any email notifications…

1. Tried the new build; same issue occurs.
2. “If you re-save the entry with the correct values in the Simple Table field will it save and work correctly the 2nd time around?” Unfortunately, no. Tested on latest version and same behavior.
3. I do not have Bloqs installed on this site. This is a basic Grid field that the Simple Table is placed within.

Hi Brian,

Yes, I can confirm that line 72 loops as you mentioned. I re-uploaded the build you shared with me to ensure it, too… from ft.simple_table.php:

/**
     * @inheritdoc
     */
    public function save($data)
    {
        $cleanData = [];
        $rowId = 1;

        if (isset($data['rows'])) {
            foreach ($data['rows'] as $row) {
                // <a href="https://boldminded.com/support/ticket/2388">https://boldminded.com/support/ticket/2388</a>
                // Inside of a Grid field the columns get out of order(?)
                ksort($row);

                // Re-index starting at 1
                if (isset($row[self::COL_HEADING_ROW])) {
                    $cleanData[$rowId][self::COL_HEADING_ROW] = $row[self::COL_HEADING_ROW];
                } else {
                    $cleanData[$rowId] = array_combine(range(1, count($row)), array_values($row));
                }

                $rowId++;
            }
        }

        return json_encode($cleanData);
    }
