我所做的是从oData服务中提取oData然后我对这些数据进行了计算，现在我想在表中显示修改后的数据。
用于修改oData并将其存储在JSON模型中的代码如下：
$.each(customers,function(i){
sum = 0;
$.each(payerName,function(j){
if (payerName[j] === customers[i] && year[j] === ySelect && mSelectKey === "a" ){
sum += amount[j];
}
else if (payerName[j] === customers[i] && year[j] === ySelect && month[j] === mSelect){
sum += amount[j];
}
});
total[i] = sum;
});
for (var i = 0; i < customers.length; i++){
tableView.push({
"customer": customers[i],
"total": total[i],
"currencyCode": currencyCode
});
}
var tableObject = {"Data": tableView};
tableModel = new sap.ui.model.json.JSONModel(tableObject);
this.setModel(tableModel, "tableModel");
我现在想在表格中显示这些数据。我尝试过以下方法，但似乎没有用：
<semantic:content>
<Table
id="customersTable"
width="auto"
items="{tableModel>/Data}"
noDataText="{worklistView>/tableNoDataText}"
busyIndicatorDelay="{worklistView>/tableBusyDelay}"
growing="true"
growingScrollToLoad="false"
updateFinished="onUpdateFinished">
<columns>
<Column id="nameColumn">
<Text text="{i18n>tableNameColumnTitle}" id="nameColumnTitle"/>
</Column>
<Column id="unitNumberColumn" hAlign="End">
<Text text="{i18n>tableUnitNumberColumnTitle}" id="unitNumberColumnTitle"/>
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<ObjectIdentifier
