### 10 Customising the result table

The output from the standard graders is a list of so-called TestResult objects, each with the following fields (which include the actual test case data):

testcode      // The test that was run (trimmed, snipped)
iscorrect     // True iff test passed fully (100%)
expected      // Expected output (trimmed, snipped)
mark          // The max mark awardable for this test
awarded       // The mark actually awarded.
got           // What the student's code gave (trimmed, snipped)
stdin         // The standard input data (trimmed, snipped)
extra         // Extra data for use by some templates


A field called result_columns in the question authoring form can be used to control which of these fields are used, how the columns are headed and how the data from the field is formatted into the result table.

By default the result table displays the testcode, stdin, expected and got columns, provided the columns are not empty. Empty columns are dropped from the table. You can change the default, and/or the column headers by entering a value for result_columns (leave blank for the default behaviour). If supplied, the result_columns field must be a JSON-encoded list of column specifiers.
