概述
本 Demo 展示了如何使用 SpreadJS 的列方向自动合并功能，自动合并列方向上内容相同的单元格。Demo 中演示了两种合并模式（自由模式和受限模式）以及两种选择模式（源单元格模式和合并单元格模式），并通过下拉菜单支持实时切换。
实现思路
初始化 SpreadJS 工作簿并加载销售数据源
配置列信息并绑定数据到工作表
使用 autoMerge 方法对整个表单区域应用列方向自动合并
监听下拉菜单的 change 事件，动态切换合并模式和选择模式
在切换模式时，先使用 direction 为 none 清除旧的自动合并，再应用新的合并设置
代码解析
应用列方向自动合并
这段代码对整个工作表应用列方向自动合并。Range(-1, -1, -1, -1) 表示整个表单区域。参数依次为：合并范围、列方向合并、受限模式、视口区域、合并单元格选择模式。
动态切换合并模式
切换模式时，先将 direction 参数设置为 none 来清除之前的自动合并设置，然后重新应用新的合并配置。使用 suspendPaint 和 resumePaint 可以避免频繁重绘，提升性能。
合并模式对比
受限模式（restricted）下，只有当前一行或前一列中的相应单元格以类似方式合并时，才会合并相邻的相同值单元格。这种方式更适合层级数据展示，能够保持数据的结构完整性。自由模式（free）则会合并所有相邻的相同值单元格，不考虑上下文关联。
运行效果
表格数据按国家、州、城市分级展示，相同内容的列单元格自动合并
通过下拉菜单可以切换合并模式：自由模式（free）或受限模式（restricted）
通过下拉菜单可以切换选择模式：选择源单元格或选择整个合并单元格
在受限模式下，合并结果更加整齐有序，符合层级数据的展示需求
API 参考
autoMerge 方法
range：自动合并的范围，使用 new GC.Spread.Sheets.Range(row, col, rowCount, colCount) 创建
direction：合并方向，可选值包括 column（列方向）、row（行方向）、columnRow（先列后行）、rowColumn（先行后列）、none（取消合并）
mode：合并模式，free（自由模式）或 restricted（受限模式）
sheetArea：工作表区域，默认为 viewport（视口区域）
selectionMode：选择模式，source（选择单个源单元格）或 merged（选择整个合并单元格）
Range 构造函数
当 row、col、rowCount、colCount 参数都为 -1 时，表示整个工作表区域。
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(_getElementById('ss'), { sheetCount: 1 });
initSpread(spread);
};
function initSpread(spread) {
var switchAutoMergeMode = _getElementById("switchAutoMergeMode");
switchAutoMergeMode.addEventListener("change", function (event) {
var range = new GC.Spread.Sheets.Range(-1, -1, -1, -1);
var sheet = spread.getActiveSheet();
sheet.suspendPaint();
//remove old auto merge range
sheet.autoMerge(range, GC.Spread.Sheets.AutoMerge.AutoMergeDirection.none);
//add new auto merge range
sheet.autoMerge(range, GC.Spread.Sheets.AutoMerge.AutoMergeDirection.column, parseInt(event.target.value), GC.Spread.Sheets.SheetArea.viewport, parseInt(switchAutoMergeSelectionMode.value));
sheet.resumePaint();
});
var switchAutoMergeSelectionMode = _getElementById("switchAutoMergeSelectionMode");
switchAutoMergeSelectionMode.addEventListener("change", function (event) {
var range = new GC.Spread.Sheets.Range(-1, -1, -1, -1);
var sheet = spread.getActiveSheet();
sheet.suspendPaint();
//remove old auto merge range
sheet.autoMerge(range, GC.Spread.Sheets.AutoMerge.AutoMergeDirection.none);
//add new auto merge range
sheet.autoMerge(range, GC.Spread.Sheets.AutoMerge.AutoMergeDirection.column, parseInt(switchAutoMergeMode.value), GC.Spread.Sheets.SheetArea.viewport, parseInt(event.target.value));
sheet.resumePaint();
//update selection when selection mode is changed after auto merge range is applied
sheet.setActiveCell(sheet.getActiveRowIndex(), sheet.getActiveColumnIndex());
});
