I've adapted a simple class based on the code found on this thread that now handles colspan and rowspan.  Not heavily tested and I'm sure it could be optimized.

Usage:

require_once('table2csv.php');

$table = '


        
      
      
      

    
    Header 1
    
    
    row 1, cell 1
    row 1, cell 2
    
    
    row 2, cell 1
    row 2, cell 2
    
    
    top left row
    top right row
    
    
    bottom right
    
    
';

table2csv($table,"sample.csv",true);

Header 1
row 1, cell 1	row 1, cell 2
row 2, cell 1	row 2, cell 2
top left row	top right row
bottom right



table2csv.php

".$i."", "", $rawHTML);
        }

        global $repeatContentIntoSpannedCells;

        $html = str_get_html(trim($rawHTML));
        $repeatContentIntoSpannedCells = $repeatContent;

        //we need to pre-initialize the array based on the size of the table (how many rows vs how many columns)

        //counting rows is easy
        $rowCount = count($html->find('tr'));

        //column counting is a bit trickier, we have to iterate through the rows and basically pull out the max found
        $colCount = 0;
        foreach ($html->find('tr') as $element) {

            $tempColCount = 0;

            foreach ($element->find('th') as $cell) {
                $tempColCount++;
            }

            if ($tempColCount == 0) {
                foreach ($element->find('td') as $cell) {
                    $tempColCount++;
                }
            }

            if ($tempColCount > $colCount) $colCount = $tempColCount;

        $mdTable = array();

        for ($i=0; $i < $rowCount; $i++) {

        $fp = fopen($filename, "w");

        foreach ($html->find('tr') as $element) {

            $colPos = 0;

                if (strpos(trim($cell->class), 'actions') === false && strpos(trim($cell->class), 'checker') === false) {
                    parseCell($cell,$mdTable,$rowPos,$colPos);
                }
                $colPos++;

            fputcsv($fp, $row);
        }
    }


    function cleanCell(&$contents,$key) {

        $contents = trim($contents);

        //get rid of pesky  's (aka: non-breaking spaces)
        $contents = trim($contents,chr(0xC2).chr(0xA0));
        $contents = str_replace(" ", "", $contents);

    function parseCell(&$cell,&$mdTable,&$rowPos,&$colPos) {
