* A simple data column definition refers to an attribute in the data model of the

|
* GridView's data provider. The name of the attribute is specified by [[attribute]].

* By setting [[value]] and [[label]], the header and cell content can be customized.

* A data column differentiates between the [[getDataCellValue|data cell value]] and the
|
|
* [[renderDataCellContent|data cell content]]. The cell value is an un-formatted value that
|
|
* may be used for calculation, while the actual cell content is a [[format|formatted]] version of that
|
|
* value which may contain HTML markup.
