2055	MergeDownCells error	wangxiuling		"'''FCKEditor2.5  IE6.0'''
MergeDownCells twice Error!
if ( tableMap[j-1] && tableMap[j-1][i] == cell )
     {

    alert(""old:""+cell.rowSpan);

     cell.rowSpan++ ;

  alert(""new:""+cell.rowSpan)

}
result is  old:1    new:1


so I changed it:
 // Disconnect all the cells in tableMap from their parents, set all colSpan and rowSpan attributes to 1.
 for ( var i = 0 ; i < tableMap.length ; i++ )
 {
  for ( var j = 0 ; j < tableMap[i].length ; j++ )
  {    
   var cell = tableMap[i][j] ;
   if ( cell.parentNode )
    cell.parentNode.removeChild( cell ) ;
   cell.colSpan = cell.rowSpan = 1 ;

//add to count cell.rowSpan:wangxiuling
                        cell.rowsCount=1;
  }
 }

// Scan by columns and set rowSpan.
 for ( var i = 0 ; i <= maxCol ; i++ )
 {
  for ( var j = 0 ; j < tableMap.length ; j++ )
  {
   if ( ! tableMap[j] )
    continue ;
   var cell = tableMap[j][i] ;
   if ( ! cell || cell._rowScanned === true )
    continue ;
                         
    if ( tableMap[j-1] && tableMap[j-1][i] == cell )

{
    cell.rowSpan++ ;

//add by wangxiuling 

cell.rowsCount++;
  } if ( ! tableMap[j+1] || tableMap[j+1][i] != cell )
    cell._rowScanned = true ;
  }
 }

 

// Insert physical rows and columns to the table.
 for ( var i = 0 ; i < tableMap.length ; i++ )
 {
  var rowObj = table.ownerDocument.createElement( 'tr' ) ;
  for ( var j = 0 ; j < tableMap[i].length ; )
  {
   var cell = tableMap[i][j] ;
   if ( tableMap[i-1] && tableMap[i-1][j] == cell )
   {
    j += cell.colSpan ;
    continue ;
   }

//add by wangxiuling
    cell.rowSpan=cell.rowsCount
   rowObj.appendChild( cell ) ;
   j += cell.colSpan ;
   if ( cell.colSpan == 1 )
    cell.removeAttribute( 'colspan' ) ;
   if ( cell.rowSpan == 1 )
    cell.removeAttribute( 'rowspan' ) ;
  }
  table.appendChild( rowObj ) ;
 }
