要将多个表绑定到一个视图，用户只需要执行以下3个步骤：
将多个表添加到DataManager
在这些表之间添加关系
添加自定义视图
以下是示例代码：
/*REPLACE_MARKER*/
/*DO NOT DELETE THESE COMMENTS*/
window.onload = function() {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 0 });
initSpread(spread);
};
function initSpread(spread) {
spread.suspendPaint();
spread.options.autoFitType = GC.Spread.Sheets.AutoFitType.cellWithHeader;
spread.bind(GC.Spread.Sheets.Events.EditStarting, function (e, args) {
if (args.sheet.getValue(0, args.col, GC.Spread.Sheets.SheetArea.colHeader) === 'Customer'){
args.cancel = true;
}
});
//init a data manager
var baseApiUrl = getBaseApiUrl();
var dataManager = spread.dataManager();
//add order table
var orderTable = dataManager.addTable("orderTable", {
remote: {
read: {
url: baseApiUrl + "/Order"
}
}
});
//add customer table
var customerTable = dataManager.addTable("customerTable", {
remote: {
read: {
url: baseApiUrl + "/Customer"
}
}
});
//add relationship between order table and customer table
dataManager.addRelationship(orderTable, "CustomerId", "customer", customerTable, "Id", "orders");
//init a table sheet
var sheet = spread.addSheetTab(0, "TableSheet1", GC.Spread.Sheets.SheetType.tableSheet);
sheet.options.allowAddNew = false; //hide new row
//bind a view to the table sheet
var style = {
formatter: 'Ship To: {{=CONCAT(@.ShipAddress, ", ", @.ShipCity)}}'
};
var relatedStyle = {
formatter: '{{=CONCAT([@customer.CompanyName], ", ", [@customer.ContactName])}}', // convert the object to string
};
var myView = orderTable.addView("myView", [
{ value: "Id", width: 100 }, //set column width 100px
{ value: "OrderDate", width: 200, style: { formatter: "MM/dd/yyyy" } },
{ value: "Freight", width: 100 },
/**
* customer.companyName - this is a related field from the customer table
* update the customerId in orderTable by select from customer table.
*/
{ value: "customer", width: 350, style: relatedStyle },
/**
* [=@] this column will contain the full row as a value, the formatter formula will extract the shipping address from the full row.
* Format functions can be used to customize column display value
* use star-size "2*" to set column width relative to the viewport width
*/
{ value: "=[@]", caption: "Address", style: style, width: "2*" }
]);
myView.fetch().then(function() {
sheet.setDataView(myView);
});
spread.resumePaint();
}
function getBaseApiUrl() {
return window.location.href.match(/http.+spreadjs\/SpreadJSTutorial\//)[0] + 'server/api';
}
