Workflow Soluiton

In Workflow 7.5 I am using the Send Email component and trying to format a table from an array.  My array is returning a cost values as a decimal.  I would like to display this value in an email as currency.  I have tried using both the "html table from collection" and the "Table from array" formatters in the email component.  There seems to be several ways to format columns but I don't see a way to format these values as currency.  Does anyone know how this can be done? 

one way off the top of my head is to format as Number(Decimal) and merge in a dollar sign.

Unfortunately, this editor doesn't let you specify a column format like the Grid UI component. One easy option I can think of is to create a second version of the data-type you're working with that has a string instead of decimal for the currency. Before the send email component iterate through your data-type to build display version with the dollar sign.

It wouldn't be a bad feature to have a format property on columns in the Build HTML Table component.
