你可以使用 showFooter 显示汇总行。 默认情况下,汇总行将显示为表格的最后一行。 你也可以使用 isFooterInserted 在数据中插入表格行。 你可以使用以下代码插入汇总行并显示下拉列表: 你还可以使用以下代码获取汇总行和下拉列表的是否可见:
window.onload = function () { var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss")); initSpread(spread); }; function initSpread(spread) { spread.suspendPaint(); var spreadNS = GC.Spread.Sheets; var sheet = spread.getSheet(0); var table = sheet.tables.add("table1", 0, 0, 5, 13, spreadNS.Tables.TableThemes.light1); table.showFooter(true); table.useFooterDropDownList(true); sheet.setActiveCell(5, 4); var dataArray = [ ["", 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'], ["Tokyo", 49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4], ["New York", 83.6, 78.8, 98.5, 93.4, 106.0, 84.5, 105.0, 104.3, 91.2, 83.5, 106.6, 92.3], ["London", 48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2], ["Berlin", 42.4, 33.2, 34.5, 39.7, 52.6, 75.5, 57.4, 60.4, 47.6, 39.1, 46.8, 51.1] ]; sheet.setArray(0, 0, dataArray); sheet.setColumnWidth(0, 120); spread.resumePaint(); _getElementById("showTotal").addEventListener('click',function () { var sheet = spread.getActiveSheet(); var table = sheet.tables.findByName("table1"); if (table) { try { table.showFooter(_getElementById("showTotal").checked); } catch (ex) { alert(!!ex.message ? ex.message : ex); } } }); _getElementById("dropdownList").addEventListener('click',function () { var sheet = spread.getActiveSheet(); var table = sheet.tables.findByName("table1"); if (table) { try { table.useFooterDropDownList(_getElementById("dropdownList").checked); } catch (ex) { alert(!!ex.message ? ex.message : ex); } } }); } function _getElementById(id){ return document.getElementById(id); }
