flextable的对应删除

com.google.gwt.user.client.ui.FlexTable

A flexible table that creates cells on demand. It can be jagged (that is, each row can contain a different number of cells) and individual cells can be set to span multiple rows or columns.

可以往 flexible 中加入String 或 Widget ，

setText(int row, int column, String text);

setWidget(int row, int column, Widget widget)

删除

removeRow(int row)

getRowCount() //Gets the number of rows.

//start
