Cell width: allows an attribute "width" to set the cell width (e.g. | or | ).
* Line breaks: Line breaks can be specified by adding a < > tag. The new line will start at the left border of the PDF document.
*
*
* Examples:
*
* Simple name+value lines:
* In most cases you will just want to display a single line per attribute with its name and value.
*
* 'myAttribute' => 'AttrName12345'
*
* This will give the following PDF output:
*
* Attribute name: 12345
*
*
* Multiline values:
* Sometimes you have multivalued attributes where it is not applicable to write all values in one line but
* where you want to list your values one below the other or show a table. This can be done by using the | tag.
*
* This example only uses one column but you can just use more | tags per tag to display more columns.
*
* 'myAttribute' => 'AttrName123 | 456 | 789 | '
