Column mappings are going to be a mapping between fields in your DataShape, defined within the parameters, to the fields in the CSV file. Each mapped column will be separated by a semi-colon. If you want to omit a field do not specify the DataShape field to map it to (see below). The field will still appear in the InfoTable but there will be no data. The columns in the CSV file must be represented by a DataShape field of the same baseType. When mapping a CSV field to a DataShape field, the order you specify the mapping must match the order the fields are, in the CSV file. For example: If your CSV file has 16 fields and you only want the first two, columnMappings: "dataShapeField1;;;;;;;;;;;;;;;dataShapeField16"
