Add support for creating Tables and applying tables styles (predefined ones or custom).

Implement pop-up providing analysis options and quick access to formatting for the selected range of cells. 

I would like to be able to hide a selected column. In excel this can be achieved by right clicking the header of a column and selecting Hide/Unhide. Actually the same goes for rows.

Implement Show Formulas command, which display the formulas in the cells instead of the result value. In MS Excel, this is available in Formulas -> Formula Auditing -> Evaluate Formula.

The keyboard shortcut is "Ctrl + ~".

Implement AutoSum command and functionality. In MS Excel, it is located in Home -> Editing -> AutoSum drop down, and allows fast creation of formula over the selected cell, by choosing a formula: SUM, AVERAGE, COUNT, MAX, MIN, etc. If a range is not selected, the command tries to predict which sells have be included.

Add support for conditional formatting of cells - allow applying of rules used during visualization of cells to automatically apply formatting depending on their values.

VLOOKUP function is similar to LOOKUP function, which is currently supported.

A list of the supported functions is available at http://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/formulas/functions

This function can be implemented as a custom function. Check the following resources for more details on how to achieve that:

- http://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/formulas/custom-functions
- https://github.com/telerik/xaml-sdk/tree/master/Spreadsheet/CustomFunctions

Available in R3 2017 Official Release Version.

Implement UI for hiding sheet. The sheets can be visible, hidden, or very hidden (could be made visible only from the API).

Note: This is already supported on model level (in RadSpreadProcessing).

At this point, the formatting can be applied only to the whole cell content.

This will enable printing with the following printing options: 

- Fit Sheet on One Page

- Fit All Columns on One Page

- Fit All Rows on One Page

- Custom automatic scaling
