Reg. freezing rows

[Abdullah Akbar]

Can any one help me with freezing rows in Google spreadsheets? i need to 
freeze the first row . My code looks like this

for (RowData rowData : workSheetData)
{
HashMap<String, String> columnData = rowData.getColumnValuesData();
ListEntry newEntry = new ListEntry();
for (String columnName : columnData.keySet())
{
if(!columnList.contains(columnName))
{
URL cellFeedUrl = worksheetEntry.getCellFeedUrl();
CellEntry pathColumnHeader = new CellEntry(1,++columnCount,columnName);
spreadSheetService.insert(cellFeedUrl, pathColumnHeader);
columnList.add(columnName);
}
newEntry.getCustomElements().setValueLocal(columnName , 
columnData.get(columnName));
}
spreadSheetService.insert(listFeedUrl, newEntry);
