Merge and Split

RichEdit controls provide support for complex tables, as well as nested ones. An end-user can insert tables, edit a table layout by splitting and merging cells, and insert rows and columns. Borders and shading can be applied individually for each cell in a table.

RichEdit provides a set of commands to work with tables. These commands can be created and executed standalone. Command bars, menus or Ribbon interface make them available to end-users, as illustrated in the following picture.

DXRichEdit_Tables

The command bar provides end users with the ability to set borders, border color and cell shading.

#Table API

You can use Table API to add, delete or modify tables programmatically. Table in a document is represented by an object with the Table inteface. To get access to rows and cells, the TableRow and TableCell interfaces are implemented. Tables are arranged in a TableCollection collection, accessible via the SubDocument.Tables property.

To get access to table contents, use Range properties of cells, rows and a table. Once you've got a document range, you can operate with it using its own methods or via the Document or SubDocument methods.
