为了快速填充几种类型的数据序列，你可以选择一些单元格并且拖拽填充柄。要使用填充柄，你需要选择那些你希望作为基础数据的单元格，然后拖拽填充柄穿过你想要填充的单元格。
你可以通过在拖拽填充柄选择一个或多个单元格的时候按下 Ctrl 键来取消自动填充。在你完成拖拽填充之后，会显示一个自动填充选项按钮。你可以点击按钮来选择如何填充选择区域。例如，你可以选择只填充格式。自动填充选项如下：
CopyCells: 使用数据对象填充的单元格，包括值，格式以及公式。
FillSeries: 连续填充单元格。
FillFormattingOnly: 只填充格式。.
FillWithoutFormatting: 只填充值，不填充格式。
你也通过拖拽回起始区域来清除填充的值。
当你拖拽填充柄时，SpreadJS 默认情况下会显示新的显示填充区域边界的提示，你可以通过以下的示例来关闭提示：
自定义填充列表
SpreadJS 通过自定义填充列表来进一步增强拖拽填充的能力。他将会根据自定义的列表来填充对应的值。
SpreadJS 内置了几种自定义列表，例如一周中的每天星期列表，一年中的月份列表。
此外，你也可以设置自定义的列表序列，例如:
window.onload = function () {
var customList = [
['Light', 'Sun', 'Moon', 'Star', 'Sky', 'Rain', 'Cloud'],
['Dog', 'Cat', 'Lion', 'Fish', 'Snake']
];
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), {sheetCount: 3});
spread.options.customList = customList;
spread.suspendPaint();
initSheet0(spread);
initsheet1(spread);
initsheet2(spread);
spread.resumePaint();
document.getElementById("chkShowDragFillTip").addEventListener('click',function() {
spread.options.showDragFillTip = this.checked;
});
document.getElementById("chkShowDragFillSmartTag").addEventListener('click',function () {
spread.options.showDragFillSmartTag = this.checked;
});
document.getElementById("dragFillType").addEventListener('change',function () {
var type = parseInt(this.value, 10);
if (!isNaN(type)) {
spread.options.defaultDragFillType = type;
}
});
};
function initSheet0(spread) {
var sheet = spread.getSheet(0);
sheet.name("Base Fill");
sheet.setValue(1, 1, "Select a cell with data below, hold your cursor over the bottom right border until you see the ‘+’,");
sheet.setValue(2, 1, "Then drag down to autofill the cell data. You can also hold the <Ctrl> key down to auto-increment the values and you can double-click to fill it automatically:");
