Point and click interaction for format

Description

As a user, I want to be able to format rows which data type is string.
These directives can be applied to specific data type. If the data type doesn't match the directive is disabled.
If the system is unable to recognize the type of data, the directives are enabled.

Operation	Data Type	Description	Requires user input	Expression
Date and Time	Date	N/A	No	Use Existing
UPPERCASE	String	UPPERCASE converts all characters in the String to uppercase	No	Use Existing
Lowercase	String	Uppercase converts all characters in the String to lowercase	No	Use Existing
TtitleCase	String	TitleCase capitalizes the first character of each word in the String	No	Use Existing
Concatenate	String	Concatenate joins together two strings (one in the column and one user provided)	Yes	<column> + <user_provided_text>
Trim Whitespace	String	Trim returns at String with leading and trailing spaces removed	No	Use Data Prep directive: trim <column>
Trim Leading Whitespace	String	Trim returns at String with leading spaces removed	No	Use Data Prep directive: ltrim <column>
Trim Trailing Whitespace	String	Trim returns at String with trailing spaces removed	No	Use Data Prep directive: rtrim <column>

Concatenate third tier input box has the following:

Text input box (hint text: Enter string)
Drop-down menu (choices: at the beginning (default); at the end)
Check box to allow the user to "Create new column" where place the results (default: the original column is affected by the directive)
