类名称：DataGrid

DataGrid介绍

[英]A tabular view with a fixed header and footer section and a scrollable data section in the middle. This widget supports paging and columns.

Columns

The Column class defines the com.google.gwt.cell.client.Cell used to render a column. Implement Column#getValue(Object) to retrieve the field value from the row object that will be rendered in the com.google.gwt.cell.client.Cell.

Headers and Footers

A Header can be placed at the top (header) or bottom (footer) of the DataGrid. You can specify a header as text using #addColumn(Column,String), or you can create a custom Header that can change with the value of the cells, such as a column total. The Header will be rendered every time the row data changes or the table is redrawn. If you pass the same header instance (==) into adjacent columns, the header will span the columns.

####页眉和页脚
页眉可以放置在数据网格的顶部（页眉）或底部（页脚）。您可以使用#addColumn（Column，String）将标题指定为文本，也可以创建可随单元格值（如列总数）更改的自定义标题。每次行数据更改或重新绘制表时，都会呈现标题。如果将相同的标题实例（=）传递到相邻列中，则标题将跨越这些列。
