Returns an array of the column information about all columns which are spanned by the column identified by sColumnId.
If there is no "parent", it returns undefined.

@param {sap.ui.table.Table} oTable Instance of the table.
@param {string} sColumnId ID of the column for which the Span-parent shall be found.
@param {int} [iLevel] level where the parent is looked up.
@returns {Array.<{column: sap.ui.table.Column, level: int}>|undefined} Array of column information.
@private
Returns an array of the column information about all columns which are spanned by the column identified by sColumnId . If there is no parent it returns undefined .
Returns an array of the children of the column
