public class WCMDataTableInputBean
extends DataTableInput
implements ParserMathObject

This class extends DataTableInput to make it easier to use in GUI builder environments. It also limits the flexibility somewhat, so that if you need the full capabilities of the superclass, then you will need to hand-code calls to its methods.

This bean provides two columns and an expanding number of rows. The columns are names "X" and "Y" by default, but you can change these names, or hide them. If you give the bean a name and add it to a parser, then you can access certain capabilities in expressions. For example, if you set the name to "data", then data.X(3) will refer to the value in the 3rd row in the X column. data.sum{X} will sum the values in column X, and data.sum(X^2) will sum the squares of the values in column X. data.count provides the number of rows. Note that these values, and any graph of the data table, are not updated while the user edits the table. You should include a WCMComputeButtonBean to cause the updates to occur.

If you need more columns, need to manually initialize the table, access row or column variables outside of a parsed expression, or read data from a file into the table, then you will need to hand-code method calls to the superclass DataTableInput.
