列样式

FlexGrid列有一些影响样式的属性:

  • cssClass:指定要添加到此列中的单元格的类名。可以在CSS规则中使用类名来修改此列中单元格的样式。
  • *align:* 指定单元格中文本的水平对齐方式。默认情况下,此属性设置为null,这会使网格根据列的 dataType选择对齐方式(数字是右对齐的,布尔值是居中的,其他类型是左对齐的)。如果要覆盖默认对齐方式,请将此属性设置为“左”,“右”或“中心”。
  • wordWrap:指定是否允许单元格中的文本在单元格中换行。请注意,除非您调用 autoSizeRows 方法,否则网格不会调整行高以适合单元格内容。

cssClass 是三个属性中最强大和最灵活的,但 alignwordWrap 简单方便。此外,alignwordWrap 适用于所有单元格,包括标题,而 cssClass 仅适用于可滚动单元格。

格式化单元格

cssClass 属性对于格式化整个列很有用。如果您必须根据其内容或其他条件格式化特定单元格,请使用 formatItem 事件。
