The Column tab is a list of all the columns that are output from the node. For each column, the Name, Data Type, Mining Type, Length, Precision and Scale (for floating point), and Column ID are displayed.
If the node has not run, the table or view structure provided by the database is displayed.
If the node has run successfully, then the structure of the sample table is displayed, based on the sampling defined when the node was specified.
There are several filtering options that limit the columns displayed. The filter settings with the (or)/(and) suffixes allow you to enter multiple strings separated by spaces. For example, if the Name/Data Type/Mining Type(or) is selected, then the filter string A B produces all columns where the name or the data type or the mining type starts with the letter A or B.
