T
- the data type of each rowpublic static class CellTable extends Object
Column
class defines the
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 Cell
.
Header
can be placed at the top
(header) or bottom (footer) of the CellTable
. 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.
