Hi Tom,
Tables of dropdowns all have the same menu options. Looking at the sample myself, I see it isn't very clear. However, the list of companies is the same for each column: skis, boots, and bindings. The example just shows different options chosen. What I am thinking you want is each column to have its own drop-down menu options.
To do this, select a “Custom Matrix” question type. Add your question title and row headers, then select “Adv. edit options for this question” before hitting Add Question. You can also access advanced edit by clicking the little notebook and pencil icon to the left of the question in the question editor.
In the advanced editor, you can scroll down to SubQuestions below the rows. Here you can add as many groups as you need columns. For each, specify the column header (group title), group type (menu/dropdown), and sub-columns (menu options).
This will give you a table of dropdowns with different dropdown menus via a custom matrix question type.
