From Jon Wong, October 1995
When a Tag contains more than one data field, the procedure for building columns in TableMaker for the secondary or tertiary etc. data fields is as follows:
In the following screen capture, you can see that the Data Class "?Gene" has a Tag field "Other_name" which contains two data fields "?Gene" and "?Reference". In order to display the "?Reference" data along with the "?Gene" data in a separate column in TableMaker, you would first create a Table definition for the Data Class "Gene" as described in the preceding section.
You must then create a Column Definition for the Tag field "Other_name" as described in the previous section. When choosing the data field from the "Tag chooser" window, you must choose "?Gene" from Tag "Other_name", since the next column you create (Other_name Reference) will be built based on the position of "?Reference" relative to "?Gene". When you've completed this Column Definition, it should look something like this:
Now, to create a column for the "?Reference" data, first create another Column Definition. Then change the "From" button to "Right of" by left-clicking on it. Then change the "1" in the next box to "2" (the data field "?Reference" is to the "Right of" the data field "?Gene", which was specified in Column Definition "2"). Be sure to hit "return" after changing the "1" to "2". Your Column Definitions should now look like this:
Next, left-click on the "Tag:" button to bring up the "Tag chooser" window. Select the "?Reference" data field. Your Column Definitions should look something like this:
By clicking on "Search Whole Class" at the top right of the Table Definition window, the Column Definitions you've made should now create a three-column table consisting of Genes, Other_names, and Other_name References:
