TableSheet 支持不同的数据规则,以帮助强调和可视化数据的变化以及控制在 TableSheet 中输入的数据类型。
TableSheet 在 TableSheet 视图中支持数据绑定条件格式和数据验证。
您可以在定义视图列信息时指定c conditionalFormat 和 validator 属性。这些属性接受下表中列出的不同类型的规则选项数组。
TableSheet 支持以下条件格式和数据验证类型。
特性 | 类型 |
---|---|
Conditional Format | AverageRule CellValueRule DataBarRule DateOccuringRule DuplicateRule FormulaRule IconSetRule SpecificTextRule ThreeScaleRule Top10Rule TwoScaleRule UniqueRule |
Data Validator | DateValidator FormulaListValidator FormulaValidator ListValidator NumberValidator TextLengthValidator TimeValidator |
以下代码示例演示如何在 TableSheet 中应用条件格式和数据验证。
// 应用条件格式formula
var formulaRule = {
ruleType: "formulaRule",
formula: "@<10",
style: {
backColor: "green",
foreColor: "lime"
}
};
// 创建数据验证器
var positiveNumberValidator = {
type: "formula",
formula: '@>0',
inputTitle: 'Data validation:',
inputMessage: 'UnitPrice cannot be less than 0.',
highlightStyle: {
type: 'icon',
color: "red",
position: 'outsideRight',
}
};
//绑定视图
myTable.fetch().then(function () {
var view = myTable.addView("myView", [
{ value: "stockItem", width: 300, caption: "Stock Item" },
{ value: "unitPrice", width: 120, caption: "Unit Price", conditionalFormats: [formulaRule], validator: positiveNumberValidator }, // apply conditional formating and data validation here
{ value: "taxRate", width: 120, caption: "Tax Rate" },
{ value: "=([@unitPrice] * [@taxRate])/100 + [@unitPrice]", caption: "Total Price", width: 150 }
]);
sheet.setDataView(view);
});
样式规则是在满足条件时应用的样式。在向数据管理器表添加视图时,可以使用GC.Data.View类中的addStyleRule添加状态规则和公式规则,或使用addView方法参数viewOptions。
下面的代码示例演示如何在TableSheet中应用状态规则和公式规则。
// 设置公式规则
var formulaRule = {
ruleType: "formulaRule",
formula: "@<=10",
style: {
borderLeft: { color: "orange", style: "medium" },
borderRight: { color: "orange", style: "medium" },
borderTop: { color: "orange", style: "medium" },
borderBottom: { color: "orange", style: "medium" }
}
};
//绑定视图
var myView = productTable.addView("myView", [
{ value: "Id", caption: "ID" },
{ value: "ProductName", caption: "Name", width: 400 },
{ value: "ReorderLevel", caption: "ReorderLevel", width: 120},
{ value: "UnitPrice", caption: "Unit Price", width: 100, readonly: true, conditionalFormats: [formulaRule] },
{ value: "UnitsInStock", caption: "Units In Stock", width: 100 },
{ value: "UnitsOnOrder", caption: "Units On Order", width: 100 }
]);
// 通过addStyleRule方法添加规则
myView.addStyleRule("lowPrice", { backColor: "green", foreColor: "white" }, {
formula: "[@UnitPrice] <= 10"
});
myView.addStyleRule("HoverStyle", { backColor: "gray", foreColor: "white" }, {
direction: GC.Data.StateRuleDirection.row,
state: GC.Data.RowColumnStates.hover
});
myView.addStyleRule("SelectedStyle", { backColor: "yellow", foreColor: "red"}, {
direction: GC.Data.StateRuleDirection.column,
state: GC.Data.RowColumnStates.selected
})
myView.fetch().then(function () {
sheet.setDataView(myView);
});
