Well, that's not exactly what Tableau is designed to do, so I wouldn't recommend trying it. Tableau is best for visualizing your data so that you can find quick insight.
As pointed out, it is not advisable to display more column in the tableau. But it is possible to display more than 16 columns. you need to modify workbook XML.
Please see below URL.
We can extend max column 16 to N number via text editor.open the .twb file in a text editor and change
<format attr=’row-levels’ value=’16’ />
