Adding Tables in DITA Topics
You can use the  Insert Table action
            on the toolbar or from the contextual menu to add a table in a DITA topic. By default,
            DITA
            supports four types of tables:

            on the toolbar or from the contextual menu to add a table in a DITA topic. By default,
            DITA
            supports four types of tables:
- DITA Simple table model - This is the most commonly used model for basic tables.
- CALS table model (OASIS Exchange Table Model) - This is used for more advanced functionality.
- DITA Choice
                     table model - This is used within a stepelement in a DITA Task document to describe a series of optional choices that a user must make before proceeding.
- DITA Properties table model - This is used in DITA Reference documents to describe a property (for example, its type, value, and description).
Since DITA is a structured format, you can only insert a table in places in the structure of a topic where tables are allowed. The Oxygen XML Developer plugin toolbar provides support for entering and editing tables. It also helps to indicate where you are allowed to insert a table or its components by disabling the appropriate buttons.
Inserting a Simple Table Model
To insert a Simple DITA table, select the  Insert Table action on the toolbar or from the
               contextual menu (or the Table submenu from the
               DITA menu). The Insert Table dialog box
               appears. Select Simple for the table
               Model.

Insert Table Dialog Box - Simple Model

The dialog box allows you to configure the following options when you select the Simple table model:
- Title
- If this checkbox is enabled, you can specify a title for your table in the adjacent text box.
- Generate table header
- If enabled, an extra row will be inserted at the top of the table to be used as the table header.
- Column widths
- Allows you to specify the type of properties for column widths
                     (colwidthattribute). You can choose one of the following properties for the column width:- proportional - The width is specified in proportional
                           (relative) units of measure. The proportion of the column is specified in a
                           relcolwidthattribute with the values listed as the number of shares followed by an asterisk. The value of the shares are totaled and rendered as a percent. For example,relcolwidth="1* 2* 3*"causes widths of 16.7%, 33.3%, and 66.7%. When entering content into a cell in one column, the width proportions of the other columns are maintained. If you change the width by dragging a column in Author mode, the values of therelcolwidthattribute are automatically changed accordingly. By default, when you insert, drag and drop, or copy/paste a column, the value of therelcolwidthattribute is1*.
- dynamic - If you choose this option, the columns are created without a specified width. Entering content into a cell changes the rendered width dynamically. If you change the width by dragging a column in Author mode, a dialog box will be displayed that asks you if you want to switch to proportional or fixed column widths.
 
- proportional - The width is specified in proportional
                           (relative) units of measure. The proportion of the column is specified in a
                           
- Frame
- Allows you to specify a value for the frameattribute. It is used to specify where a border should appear in the table. The allowed values are as follows:- none - No border will be added.
- all - A border will be added to all frames.
- top - A border will be added to the top frame.
- topbot - A border will be added to the top and bottom frames.
- bottom - A border will be added to the bottom frame.
- sides - A border will be added to the side frames.
- -dita-use-conref-target - Normally, when using a
                           conref, the values of attributes specified locally are preserved. You can choose this option to override this behavior and pull the value of this particular attribute from theconreftarget.

Note
When you click Insert, a simple table is inserted into your document at the current cursor position.
Inserting a CALS Table Model (OASIS Exchange Table)
To insert an OASIS Exchange Table (CALS), select the  Insert Table action on the toolbar or from the
               contextual menu (or the Table submenu from the
               DITA menu). The Insert Table dialog box
               appears. Select CALS for the table Model. This
               model allows you to configure more properties than the Simple model.

If you change the width by dragging a column in Author mode, a dialog box will be displayed that asks you if you want to switch to proportional or fixed column widths.
- fixed - The width is specified in fixed units. By default,
                           the ptunit is inserted, but you can change the units in the colspecs (column specifications) section above the table or in Text mode. The following units are allowed:pt(points),cm(centimeters),mm(millimeters),pi(picas),in(inches).

Note
When you click Insert, a CALS table is inserted into your document at the current cursor position.
When you insert a CALS table, you see a link for setting the colspecs
               (column specifications) of your table. Click the link to open the controls that allow
               you to
               adjust various column properties. Although they appear as part of the Author mode, the
               colspecs link and its controls will not appear in your output. They are
               just there to make it easier to adjust how the columns of your table are formatted.

Editing an Existing Table
You can edit the structure of an existing table using the table buttons on the toolbar (or in the contextual menu) to add or remove cells, rows, or columns, and to set basic table properties. Additional attributes can be used to fine-tune the formatting of your tables by using the Attributes view (). See the DITA documentation for a full explanation of these attributes.
You can also use the  Table Properties (Ctrl + T (Command + T on
                        OS X))
               action from the toolbar or contextual menu (or DITA menu) to modify many of the properties of

Also, remember that underneath the visual representation, both table models are really just XML. If necessary, you can edit the XML directly by switching to Text mode.
