This is clearly a bug! Whenever a table contains a content control that cannot be deleted, the user cannot insert a column anywhere in the table, and the (row) Insert Above and Insert Below command do not function if the selected row contains a locked content control (red area in illustration below). Notice that no row or column is inserted. With the cursor in the cell containing the content control, click the "Table Tools Layout" tab and then click either "Insert Above, Insert Below, Insert Right or Insert Left" in the "Row & Columns" group.In the center cell, add a plain text content control and set the set the control property "Content control cannot be deleted.".Add new 5 row x 5 column table to a Word document. To add text fields to your Word document, follow the steps below.Use a StyleRef field to copy information from the body to headers and footers. Insert document information (properties) in your document body or headers and footers. Apply field switches to change how the field result appears on the page. This setting results in some odd behavior in Word. Insert the name of the file (FILENAME) with the path or not. Each of the content controls in the demonstration table have their property "Content control cannot be deleted" set. In this case, unless your users are Word power users and knowledgeable of certain buggy behavior Word, you certainly won't get good results! You probably won't find much enthusiasm for providing just a couple of rows and asking your users to copy and paste new rows if required. Not enough can frustrate your users, and too many can look unprofessional or add work (deleting unused rows) for you or the document users. As the document designer, you are faced with the decision of how many rows to provide. However, other users may require two, three, or even two dozen table rows to provide the information requested. Just for the purpose of demonstration, the cells containing the combo box and dropdown list also contain fixed text. I've included demonstrations of the seven content controls available in Word 2010 for displaying data rich text, plain text, picture, combo box, dropdown list, date and checkbox. Each cell contains for one or more content controls for entering variable data.
Easy for me, as this old goat, only has one grandchild.
