SpreadJS 允许您通过添加、删除和修改表格样式来管理自定义数据透视表主题,然后将这些样式应用于您的数据透视表。要应用这些样式,您只需为数据透视表设置一个样式名称
您可以使用 GC.Spread.Sheets.WorkBook
类的 customPivotTableThemes
属性来自定义数据透视表样式
CustomPivotTableThemesManager
类提供了以下方法来管理自定义数据透视表主题:
all
: 获取所有自定义数据透视表主题
get
: 通过名称获取特定的自定义数据透视表主题
add
: 使用样式对象或名称添加新的自定义数据透视表主题
remove
: 通过名称删除自定义数据透视表主题
update
: 通过名称或样式对象更新现有的自定义数据透视表主题
此外,GC.Spread.Sheets.WorkBook
类的 defaultPivotTableTheme
方法允许您有效地管理默认的数据透视表样式,以确保所有数据透视表具有一致的外观和感觉
type=warning
注意事项:
数据透视表样式名称必须唯一
例如,如果您已经有一个名为 "TEST" 的自定义数据透视表样式,则不能创建另一个具有相同名称的数据透视表样式
数据透视表样式名称不区分大小写
当将样式名称添加到数据透视表时,它会通过名称查找样式
如果样式名称匹配内部样式,它将直接应用。如果不匹配,它将搜索 customStyles 集合中的相应样式。如果找到,将应用该样式,否则将使用默认样式
defaultPivotTableTheme 应该是表示数据透视表样式名称的字符串
如果创建数据透视表时未明确指定样式,并且存在具有此默认名称的样式,则该样式将应用于该数据透视表
自定义数据透视表主题不支持旧版本的 Excel IO
以下代码示例演示了管理自定义数据透视表主题的不同方法
添加新的数据透视表主题:
const spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
// 添加一个名为 "custom0" 的新数据透视表主题
const pivotTableStyle = spread.customPivotTableThemes.add("custom0");
const firstColumnStripeStyle = new GC.Spread.Pivot.PivotTableStyle();
firstColumnStripeStyle.backColor = "skyblue";
pivotTableStyle.firstColumnStripeStyle(firstColumnStripeStyle);
获取数据透视表主题:
// 获取数据透视表主题
const pivotTableStyle = spread.customPivotTableThemes.get("custom0");
应用数据透视表主题:
// 创建数据透视表
const sourceData = [["Date","Buyer","Type","Amount"],
["01-Jan","Mimi","Fuel",74],
["15-Jan","Mary","Food",235],
["17-Jan","Denny","Sports",20],
["21-Jan","Kelly","Books",125]];
activeSheet.setArray(0, 0, sourceData);
activeSheet.tables.add('sourceData', 0, 0, 5, 4);
// 设置数据透视表主题
const pivotTable = activeSheet.pivotTables.add(
"pivottable1",
"sourceData",
1,
1,
GC.Spread.Pivot.PivotTableLayoutType.compact,
GC.Spread.Pivot.PivotTableThemes.medium2
);
// 将样式应用于数据透视表
pivotTable.theme("custom0");
修改数据透视表主题:
当您对现有的数据透视表样式进行更改时,它会自动更新所有之前应用了该样式的表格
// 修改数据透视表主题
const pivotTableStyle = spread.customPivotTableThemes.get("custom0");
pivotTableStyle.firstColumnStripeStyle().backColor = "red";
// 更新数据透视表主题
spread.customPivotTableThemes.update("custom0", new GC.Spread.Pivot.PivotTableTheme());
删除现有主题:
当您删除自定义数据透视表样式时,所有使用该已删除样式的表格将切换到默认样式
// 删除数据透视表主题
spread.customPivotTableThemes.remove("custom0");
设置默认主题:
// 设置默认数据透视表主题
spread.defaultPivotTableTheme("custom0");
您还可以使用 SpreadJS Designer 组件通过以下步骤格式化自定义数据透视表样式:
单击 DESIGN > PivotTable Styles 组中的 PivotTableStyles 按钮
单击下拉箭头并选择 "New Pivot Table Style.." 选项,通过设置所需的样式元素来添加新的数据透视表样式
所有用户创建的数据透视表样式显示在数据透视表样式集合列表的 Custom 部分下
右键单击自定义数据透视表样式,并根据需要执行应用、修改、复制、删除和设置为默认等操作
type=warning
注意:您不能修改或删除内置的数据透视表样式
