Export ASCII to support ignore empty columns

Version: 2018b

Type: Features

Category: Data Handling

Subcategory: Workbook and Worksheet

Jira: ORG-17790

Add a checkbox named as "Ignore Ending Empty Columns", to control ascii export, to ignore empty columns from the end, with the following options:

0 = no ignore (current way, default)

1 = ignore all empty columns after the last column with data, meta data not considered, and column with all missing values are considered empty.

This is used only if export selection is not chosen.
