More Options for Export Component Tables in Analytics

Add the possibility for the user to choose which columns of a component table will be exported. Background: sometimes the user does not want to import the entire text file, but only selected rows of the table. This will not work with the export file, since it contains many columns which are not displayed in the component table. For this, it would be helpful to export a component table, but with option to export only visible columns. Then the user could simply copy a row from the export file and directly copy it into a new or an existing component table, without the need to adjust the columns of the text file to the visible columns in Analytics.
