文本省略符 | 功能示例 | SpreadJS 在线示例

概述本 Demo 展示了如何使用 showEllipsis 属性控制单元格文本溢出时的省略号显示,以及该属性与文本对齐、缩进、垂直文本和单元格内边距等样式的协同效果。Demo 提供了交互式面板,用户可以选中单元格后动态调整各种样式属性,观察省略号的显示效果变化。实现思路使用 fromJSON 加载预定义的表格数据,初始化 Spread 工作簿通过 getActualStyle() 获取当前选中单元格的实际样式对象根据用户操作修改样式对象的属性(showEllipsis、hAlign、vAlign、textIndent、isVerticalText、cellPadding) 使用 setStyle() 将修改后的样式应用到选中单元格为每个样式控制按钮绑定点击事件处理函数代码解析设置省略号显示这段代码获取选中单元格的当前样式,将 showEllipsis 属性设置为 true,然后应用样式。当文本超出单元格边界时,会显示省略号而不是溢出到相邻单元格。设置水平对齐水平对齐值使用数字常量:0 表示左对齐,1 表示居中对齐,2 表示右对齐。对齐方式会影响省略号的位置和文本显示区域。设置文本缩进文本缩进会增加文本与单元格边界的距离,从而影响省略号的显示位置。代码检查当前缩进值,递增后更新样式。设置单元格内边距 cellPadding 属性接受类似 CSS 的格式字符串("上右下左"),为单元格内容设置内边距,进一步影响文本显示区域和省略号位置。运行效果点击"显示"按钮,选中单元格的文本溢出时会显示省略号;点击"移除"按钮取消省略号显示调整水平对齐(左对齐、居中、右对齐)和垂直对齐(顶部、居中、底部)可以改变省略号的位置增加或减少文本缩进值,观察缩进对省略号显示的影响点击"垂直"按钮切换到垂直文本模式,点击"正常"按钮恢复水平文本设置单元格内边距(上、右、下、左),观察内边距对文本显示区域的影响当鼠标悬停在显示省略号的单元格上时,会自动弹出提示显示完整文本内容 API 参考 showEllipsis 属性类型:undefined | boolean 作用:控制文本超出边界时是否显示省略号设置为 true 时,溢出文本被剪切并显示省略号,悬停时会显示完整文本的提示 getActualStyle 方法 row:行索引 col:列索引 sheetArea:可选,表单区域返回值:单元格的实际样式对象 setStyle 方法 row、col:单元格位置 style:样式对象 sheetArea:可选,表单区域相关样式属性 hAlign:水平对齐(0=左对齐,1=居中,2=右对齐) vAlign:垂直对齐(0=顶部对齐,1=居中,2=底部对齐) textIndent:文本缩进量 isVerticalText:是否为垂直文本 textOrientation:文本旋转角度 cellPadding:单元格内边距,格式为"上右下左"
