How do I create currency and percentage columns in WordPress tables?

How do currency, percentage and similar columns work in wpDataTables?

Instead of many extra column types, wpDataTables adds a prefix and a suffix to each cell value, which keeps sorting and filtering intact.

• Adding all these examples as column types would make the plugin usage confusing for users, so we found a different solution: we added a “Cell content prefix” and a “Cell content suffix” block for each of the column settings.
• Whatever you enter in the “Cell content prefix” (for example a $, or other currency sign) will be rendered in each cell of this column before the actual cell value; whatever you enter in the “Cell content suffix” (for example “%” or “pcs.”) will be rendered after the actual cell value. These entrees will not affect sorting, filtering, or any other column functions.
