使用以下代码创建一个buttonList单元格：
ButtonList Cell Type 包括 items, isFlowLayout, maxRowCount, maxColumnCount, itemSpacing, 和 direction 等方法, 与 Radio List Cell Type 和 Checkbox List Cell Type 类似。
你可以使用 padding 方法以类似于css的格式以像素为单位获取或设置padding。
你可以使用 selectedBackColor 和 selectedForeColor 方法配置已选择的样式。
你可以使用 selectionMode 方法设置单选或者多选模式。
