Grid.addColumn介绍

[英]Adds a new text column to this Grid with a value provider. The column will use a TextRenderer. The value is converted to a String using Object#toString(). In-memory sorting will use the natural ordering of elements if they are mutually comparable and otherwise fall back to comparing the string representations of the values.
[中]使用值提供程序将新文本列添加到此网格。该列将使用TextRenderer。使用对象#toString（）将值转换为字符串。内存中排序将使用元素的自然排序，如果它们相互比较，则返回到比较值的字符串表示形式。
