自动合并单元格

SpreadJS支持自动合并功能,允许用户自动合并包含重复文本的相邻单元格。 在自动合并操作期间,在此过程中不会丢失任何数据。

使用自动合并的好处

自动合并功能可帮助用户:

  • 在大型数据集中创建清晰可视化。
  • 合并相同的单元而不会丢失任何数据。
  • 消除冗余(重复文本)以消除表单中不必要的混乱。
  • 节省大量时间和精力,而无需手动扫描重复的单元格以将它们一一合并。

自动合并原理?

自动合并功能会自动合并具有相同文本的连续单元格,并调整合并单元格的文本位置。

此功能在您要合并的单元格不应属于任何跨度范围的条件下起作用。 使用SpreadJS时,用户可以使用 autoMerge() 方法 将自动合并功能应用于指定范围,包括范围,行,列和整个表单。

SpreadJS 支持以下两种模式 AutoMergeMode 枚举:

  • 自由模式-在此模式下,具有相同值的单元格会自动与相邻的单元格合并。
  • 受限模式-在此模式下,只有在前一行或前一列中的相应单元格以类似方式合并时,具有相同值的单元格才会与相邻单元格合并。

要在SpreadJS中使用 addSpan 的选择功能支持自动合并, 使用 Worksheet 类下的 autoMerge 方法的参数 SelectionMode

您可以将 SelectionMode 参数设置为 sourcemerged 。 下面介绍了这两个选项:

  • source : 在此模式选项中,您可以选择自动合并区域中的单个单元格。
  • merged : 在此模式选项中,您可以在自动合并区域中选择整个合并的单元格。

使用场景

在表单上执行数据分析时,用户可能希望合并包含相同文本的多个单元格,以增强数据表示和更好的结构。

例如-在生成销售报告时,最好将匹配的州或城市名称自动合并在一起,使其看起来更整洁,干净,同时确保不会丢失任何信息,并且合并后的单元格中的数据保持完整。

以下截图描述了自动合并操作如何在表单中组合国家,州和城市的名称。

自动合并单元格与生成和合并单元格

在表单中执行“自动合并单元格”操作和“跨单元合并”的基本区别是:

  • 在SpreadJS中使用“自动合并”功能时,即使执行了合并操作,单元仍保持可导航和可编辑状态。 相反,在执行单元格的合并和合并时,变更单元格值时会自动调整跨度和合并的单元格。
  • 当用户滚动浏览表单时,文本在合并的跨度中保持可见(粘滞)状态。 与常规合并跨度不同,自动合并的像元具有相同的值。

注意: 使用自动合并功能时,必须牢记以下限制:

代码

以下代码段使用合并包含相同国家名称,州和城市的单元格 autoMerge() 方法。
