When using multiple data tables and trying custom expression there is no way to manually select the data table from which to select the column. You can change the data table that is shown on the custom expression menu by going to Edit>Data table Properties and selecting the table you wish to set as default, but there is no way to do this directly from the custom expression menu. This would be helpful when using multiple data tables and the users need to create custom expression using columns from different data tables.
