切片器设置 | 功能例子 | SpreadJS JavaScript 学习指南

disableResizingAndMoving: 当 'disableResizingAndMoving' 为 true 时, 无法通过鼠标来改变切片器位置和大小，但是切片器依然可以通过鼠标来筛选数据。 isLocked: 当表单未被保护时，切片器的 'isLocked'属性不起作用。当表单被保护时并且切片器 'isLocked' 为 true 时，切片器无法被鼠标选中，此时，切片器也不能通过鼠标来筛选数据。 fixPosition: 当 'fixPosition' 为 true 时，切片器的位置不会因为滚动，行列可见性，行列高宽改变，行列移动等改变自己的位置。 sortState: 表明切片器中数据排序的状态。类型为 GC.Spread.Sheets.SortState。默认值为GC.Spread.Sheets.SortState.ascending。 dynamicMove and dynamicSize: 当表单的行列宽度改变时，切片器的位置行为会因这两个属性不同而不同。随着单元格移动及改变大小： 'dynamicMove' 为 true 并且 'dynamicSize' 为 true。随着单元格移动但不改变大小： dynamicMove' 为 true 并且 'dynamicSize' 为 false。不随着单元格移动且不改变大小： 'dynamicMove' 为 false 并且 'dynamicSize' 为 false。 style: Spread.Sheets支持14种内置切片器样式。你可以使用这些内置样式来改变切片器的外观：切片器默认样式是 GC.Spread.Sheets.Slicers.SlicerStyles.light1().
