# Constant Data Column
> [HTML Version](constantdatacolumn.htm)
_Added August 2015_
**data= **
This allows you to define the contents of a column that is constant for all rows. This is essentially just a shortcut to redundantly specifying the same text in every row of the data array, and is typically most useful for columns containing "buttons", such as a "delete item" button on any row. Aside from specifying the column contents in the Data= clause, you must also set the _cpos_ and _cformat_ parameters to -1.
For example, you can define a column of delete "buttons" as follows:
coldef += "-1~-1~Del~I~ImgSiz=16,16,24~ImgCount=1~Data=delete2::ashico1~ClickExit=-300,0~~"
