基本应用

SpreadJS支持数据透视表,数据透视表支持排序、筛选等多种功能,可以按不同维度分析数据,并且支持多种主题。

SpreadJS 数据透视表支持两种格式的数据源: table name: 数据透视表使用一个表格的名字去获取数据源。 range formula: 数据透视表使用工作表的一个范围公式获取数据,这个范围公式必须是工作表的绝对路径。 使用数据透视表,请添加如下链接到文档的开始部分: 使用一个表格名称去创建一个数据透视表: 使用工作表的一个范围公式创建数据透视表: 如果被数据透视表使用的数据源发生了改变,并且数据透视表需要更新数据源,你可以通过下面这个方法更新数据源:
window.onload = function () { let spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), {sheetCount: 4}); initSpread(spread); }; function initSpread(spread) { spread.suspendPaint(); let sheet1 = spread.getSheet(0); let sheet2 = spread.getSheet(1); let sheet3 = spread.getSheet(2); let sheet4 = spread.getSheet(3); let tableName = getDataSource(sheet4, pivotSales); initPivotTable(sheet1, tableName); addCustom(sheet2, tableName); initBlankPivot(sheet3, tableName); columnFit(sheet4,0,6,100); spread.resumePaint(); } function getDataSource(sheet, tableSource){ sheet.name("DataSource"); sheet.setRowCount(117); sheet.getCell(-1, 0).formatter("YYYY-mm-DD"); sheet.getRange(-1,4,0,2).formatter("$ #,##0"); let table = sheet.tables.add('table', 0, 0, 117, 6); for(let i=2;i<=117;i++) { sheet.setFormula(i-1,5,'=D'+i+'*E'+i) } table.style(GC.Spread.Sheets.Tables.TableThemes["none"]); sheet.setArray(0, 0, tableSource); return table.name(); } function addCustom(sheet, tableName){ sheet.name("Custom PivotTable"); sheet.setRowCount(1000); let pivotTableOptions = {bandRows:true,bandColumns:true}; let pivotTable = sheet.pivotTables.add("CustomPivotTable", tableName, 1, 1, GC.Spread.Pivot.PivotTableLayoutType.tabular, GC.Spread.Pivot.PivotTableThemes.light8, pivotTableOptions); pivotTable.suspendLayout(); pivotTable.add("salesperson", "Salesperson", GC.Spread.Pivot.PivotTableFieldType.rowField); pivotTable.add("car", "Cars", GC.Spread.Pivot.PivotTableFieldType.rowField); pivotTable.add("date", "Date", GC.Spread.Pivot.PivotTableFieldType.columnField); pivotTable.add("total", "Totals", GC.Spread.Pivot.PivotTableFieldType.valueField, GC.Pivot.SubtotalType.sum); let itemList = ["Alan","John", "Tess"]; pivotTable.labelFilter("Salesperson", { textItem: { list: itemList, isAll: false } }); pivotTable.sort("Salesperson", { sortType: GC.Pivot.SortType.asc }); let carList = ["Audi","BMW","Mercedes"]; pivotTable.labelFilter("Cars", { textItem: { list: carList, isAll: false } }); pivotTable.sort("Cars", { sortType: GC.Pivot.SortType.asc }); let style = new GC.Spread.Sheets.Style(); style.formatter = "$ #,##0"; pivotTable.setStyle({dataOnly: true}, style); pivotTable.resumeLayout(); pivotTable.autoFitColumn(); } function initBlankPivot(sheet, source){ sheet.name("Blank PivotTable"); sheet.setColumnWidth(0, 20); sheet.pivotTables.add("BlankPivotTable", source, 1, 1, GC.Spread.Pivot.PivotTableLayoutType.outline, GC.Spread.Pivot.PivotTableThemes.medium4); } function initPivotTable(sheet, tableName){ sheet.name("Basic PivotTable"); sheet.setRowCount(1000); let pivotTableOptions = {bandRows:true,bandColumns:true}; let pivotTable = sheet.pivotTables.add("PivotTable", tableName, 1, 1, GC.Spread.Pivot.PivotTableLayoutType.outline, GC.Spread.Pivot.PivotTableThemes.medium1, pivotTableOptions); pivotTable.suspendLayout(); pivotTable.add("salesperson", "Salesperson", GC.Spread.Pivot.PivotTableFieldType.rowField); pivotTable.add("car", "Cars", GC.Spread.Pivot.PivotTableFieldType.rowField); pivotTable.add("date", "Date", GC.Spread.Pivot.PivotTableFieldType.columnField); let groupInfo = { originFieldName: "date", dateGroups: [{ by: GC.Pivot.DateGroupType.quarters }] }; pivotTable.group(groupInfo); pivotTable.add("total", "Totals", GC.Spread.Pivot.PivotTableFieldType.valueField, GC.Pivot.SubtotalType.sum); let style = new GC.Spread.Sheets.Style(); style.formatter = "$ #,##0"; pivotTable.setStyle({dataOnly: true}, style); pivotTable.resumeLayout(); pivotTable.autoFitColumn(); } function columnFit(sheet,start,end,width){ for (let i = start; i < end; i++) { sheet.setColumnWidth(i, width); } }
