下面的示例展示了如何用SpreadJS轻松地创建复杂输入表单，比如1040表单（美国个人所得税的纳税申报表）。

这个示例主要使用了锁定单元格来阻止编辑行为、竖直对齐，还通过fromJSON加载了预定义的模板。

app.js:

window.onload = function () {
            var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 1 });
            initSpread(spread);
        };

        function initSpread(spread) {
            var sd = data;
            if (sd.length > 0) {
                if (!spread) {
                    return;
                }
                spread.suspendPaint();
                spread.fromJSON(sd[0]);
                spread.options.tabStripVisible = false;

                var sheet = spread.getSheet(0);

                sheet.options.isProtected = true;
                sheet.options.gridline = { showHorizontalGridline: false, showVerticalGridline: false };
                sheet.getRange(-1, 0, -1, sheet.getColumnCount(GC.Spread.Sheets.SheetArea.rowHeader), GC.Spread.Sheets.SheetArea.rowHeader).visible(false);
                sheet.getRange(0, -1, sheet.getRowCount(GC.Spread.Sheets.SheetArea.colHeader), -1, GC.Spread.Sheets.SheetArea.colHeader).visible(false);

                var style = sheet.getStyle(1, 1, GC.Spread.Sheets.SheetArea.viewport);
                if (style) {
                    style.wordWrap = true;
                    sheet.setStyle(1, 1, style);
                }

                style = sheet.getStyle(3, 3, GC.Spread.Sheets.SheetArea.viewport);
