在新窗口中打开演示可以打开设计器：
报表支持使用公式(R.V)获取任何扩展单元格的值。您可以使用此公式计算任何您想要的统计数据（例如YOY、MOM、百分比、累积等）。
函数
可用的函数如下：
R.V(cell, [offset | context_cell | "CurrentPage"])，通过偏移或上下文获取特定扩展单元格的值。
R.A(cell, offset)，绝对偏移，此函数只能用作R.V函数的参数。
R.R(cell, offset)，相对偏移，此函数只能用作R.V函数的参数。
基本用法
例如，如果单元格A2绑定到年份列，B2绑定到月份列，C2绑定到销售列，则函数的行为如下：
R.V(C2)将返回C2单元格的所有值作为数组，因此您可以使用SUM(R.V(C2))获取C2单元格所有值的总和。
R.V(C2, A2)将返回当前年份的所有销售值作为数组。
C2/SUM(R.V(C2, A2))将返回当前月份的销售额占当年销售额的百分比。
R.V(C2, R.A(A2, 1), R.A(B2, 5))将返回第一年的第五个月的销售额。
R.V(C2, R.A(A2, 2), R.A(B2, 2))将返回第二年的第二个月的销售额。
R.V(C2,R.R(B2,-1))将返回上个月的销售额。
从Spread JSON创建示例
此报表使用fromJSON加载预定义的模板。您可以在新窗口中打开示例，以查看设计器中的报表设置。
window.onload = async () => {
const loadingTip = addLoadingTip();
const { spread, designer } = createSpreadAndDesigner();
const res = await fetch('$DEMOROOT$/zh/sample/features/report-sheet/formula/hierarchical-cell-index/get-value/spread.json');
await spread.fromJSON(await res.json());
loadingTip.remove();
if (designer) {
designer.refresh();
}
};
function createSpreadAndDesigner() {
const demoHost = document.getElementById('demo-host');
if (window !== top) {
return {
spread: new GC.Spread.Sheets.Workbook(demoHost, { sheetCount: 1 }),
};
} else {
const designer = new GC.Spread.Sheets.Designer.Designer(demoHost, undefined, undefined, { sheetCount: 1 });
return {
designer,
spread: designer.getWorkbook(),
};
}
}
function addLoadingTip() {
const div = document.createElement('div');
div.style.position = 'absolute';
div.style.inset = '0';
div.style.display = 'flex';
div.style.alignItems = 'center';
div.style.justifyContent = 'center';
div.style.background = 'white';
div.style.zIndex = '100';
div.textContent = 'Loading data from server ...';
document.body.appendChild(div);
return div;
