RowFilter的信息和SheetTable的过滤对话框上的检查状态与附在TableSlicerData上的Slicers的过滤结果同步。所有的切片器（与TableSlicerData相连）都会收到onFilter通知，并在SheetTable用代码或过滤对话框完全过滤后获得过滤的结果。
你可以按以下方式使用TableSlicerData。
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
var sheet = spread.getActiveSheet();
// Define data source.
var columnNames = ["Name", "Sex", "City", "Birthday"],
data = [
["Bob", "Man", "NewYork", "1968/06/08"],
["Betty", "Woman", "Washington", "1972/07/03"],
["Alice", "Woman", "Atlanta", "1964/03/02"],
["Tom", "Man", "Houston", "1986/12/03"],
["Jenny", "Woman", "Washington", "1956/10/13"],
["Nacy", "Woman", "NewYork", "1989/01/14"],
["John", "Man", "Houston", "1995/01/01"],
["Mark", "Man", "Atlanta", "1965/11/11"],
["Susan", "Woman", "Atlanta", "1983/07/08"]];
// Create a table.
var table = sheet.tables.addFromDataSource("table1", 1, 1, data);
table.setColumnName(0, columnNames[0]);
table.setColumnName(1, columnNames[1]);
table.setColumnName(2, columnNames[2]);
table.setColumnName(3, columnNames[3]);
sheet.getRange(-1, 1, -1, 6).width(80);
// Get TableSlicerData from table.
var slicerData = table.getSlicerData();
// Create a custom slicer and add it to dom tree.
var slicer1 = new CustomSlicer(document.getElementById("cityContainer"),'City');
slicer1.setData(slicerData, "City");
var slicer2 = new CustomSlicer(document.getElementById("sexContainer"),'Sex');

this.slicerData.attachListener(this);
this.onDataLoaded();
}
CustomSlicer.prototype.onDataLoaded = function () {
var columnName = this.columnName,

}
div.innerHTML= domString;
this.container.appendChild(div);
// Attach events to dom element.
var self = this;
document.querySelector('.options-container').addEventListener('change',function (e) {
// Invoke getExclusiveData method to get exclusive data from slicerData.
var exclusiveData = self.slicerData.getExclusiveData(self.columnName);
// parent = this.parentNode.parentNode;

indexes = [];
for (var i = 0, length = items.length; i < length; i++) {

var value = items[i].value;

value = parseInt(value);
