表尾合并

通过 footerData 与 footerMerges 展示多行表尾并合并单元格。

使用的 API

type Column = {
  key: string;  // 列标识(必填)
  title: string;  // 列标题(必填)
  width: number;  // 列宽(必填)
}

type Options = {
  list: T[];  // 数据列表
  itemKey: string;  // 行唯一标识字段名
  estimatedSize: number;  // 行预估高度(px)
  buffer: number;  // 缓冲区行数
  border: boolean;  // 是否显示边框
  footerData: string[][];  // 表尾数据
  footerMerges: MergeCell[];  // 表尾合并单元格
}

  status.textContent = `表尾合并：${list.length} 行 × ${colCount} 列（两行表尾 + 合计/平均跨列合并）`;

  return () => {
    table.destroy();
    root.innerHTML = '';
