示例1: addColumn
/**
* Add a column to a table workspace filled with double values
* calculated with a function wich uses another numeric column as its x values.
* @param tws :: The table workspace.
* @param xColumn :: Name of the column with the x-values. Must exist and be numeric
* @param yColumn :: Name of a column to store the calculated values. If a column with
* this name exists it will be overwritten if numeric or exception thrown otherwise.
* If the column doesn't exist it will be created.
* @param fun :: A function to calculate the values.
