I write a lot of programs for clients, i use a table system to input the exercise name, picture information and about 3 other columns.
my qeustion is, in one of the columns I have a description of how to do the exercise. Instead of writing this description out every single time for every new program, is there a way to have that cell of the table reference a generic file that I have, that will automatically input the information for that exercise into the table cell? and this is before printing, most of the times I will convert to a pdf and then email the program to the client.
You could use the text clippings feature of the Mac OS. Select the text you want to keep (I chose your second paragraph above), then drag it to the desktop. It will be saved to the Desktop as a clipping, with a name generated from the first few words of the text.
Once saved, you can rename the file, and move it to a folder where you keep clipping on this topic.
To use the clipping, select the file and drag it into the document where you want to use it. For the example, I've renamed the file as shown:
Then dragged that file into a Pages document, on the line after the words "File here".
If you have several pieces of boiler plate like this, place them into a folder after renaming each to say what it contains,
Open a new blank Pages document.
Layout the table, including formatting and the static text that provides instructions for the given exercise in the desired table column.
Now name and save this document as a Pages Template. By default, it is saved in the following location, where it will be referenced under a new category: My Templates, by the Pages Template Chooser on launch.
~/Library/Application Support/iWork/Pages/Templates/My Templates/
Otherwise, you may also tell Pages to save these custom exercise templates into a folder name and location of your choice. This folder name will appear as the template category in the Template Chooser. I would prefer this option as access is easier for template changes.
Pages will assign a .template file extension and a different Pages document icon. You also have the option of displaying the template contents in the Template Chooser.
New customer documents would be creating by specifying the appropriate exercise template from template folder name in the Template Chooser. This makes it easy to provide the right boilerplate for the desired exercise.
