        var value = evaluator.getValue(row, col);

        if(value !== null && value >= 10 && value <= 50){
            //Return True only when the following conditions are satisfied.
            //　(1)Values are entered.
            //　(2)Values are not lower than 10.
            //　(3)Values are not greater than 50.
            return true;

$(document).ready(function(){
    var spread = new GcSpread.Sheets.Spread($("#ss").get(0),{sheetCount:3});
    var activeSheet = spread.getActiveSheet();

    activeSheet.setValue(0, 0, 10);
    activeSheet.setValue(1, 0, 100);
    activeSheet.setValue(2, 0, 50);
    activeSheet.setValue(3, 0, 40);
    activeSheet.setValue(4, 0, 80);
    activeSheet.setValue(5, 0, 1);
    activeSheet.setValue(6, 0, 65);
    activeSheet.setValue(7, 0, 20);
    activeSheet.setValue(8, 0, 30);
    activeSheet.setValue(9, 0, 35);

    //Set a row Filter.
    var rowFilter = new GcSpread.Sheets.HideRowFilter(new GcSpread.Sheets.Range(0, 0, 7, 1));
    activeSheet.rowFilter(rowFilter);
    rowFilter.addFilterItem(0, new CustomFilter());
    rowFilter.filter(0);
