The following are personal observations about tables. Not from PTC or any documentation.
* Table size is based on the drawing_text_height (DTH) and text_width_factor (TWF) drawing options at the time of table creation
* Character height space claim
o First character = DTH * 2.0
o Additional character = DTH * 1.5
* Character width space claim
o First character = DTH * 2 * TWF
o Additional characters = DTH * TWF
* These height and width space claims are used to determine the table row and column sizes
* Horizontal and Vertical alignment settings for the text in each cell will not violate these buffer areas.
o For example, if a table cell is 1 character wide, and 1 character tall, (and the text height and width factor match the DTH and TWF used when the table was created), then changing the H or V alignment will have no effect.)
o If you want to be able to move the text closer to the edges of the table, create the table with the DTH initially set smaller than what you actually intend to use.
* By setting a table to one character tall, and then dividing the height in drawing units in half, you can determine what the initial DTH value was when the table was originally created.
* Using the variant_drawing_item_sizes config option will allow you to resize a table. This resize effectively changes the DTH and TWF that were originally set at the time of table creation to some new value. (Since row height and column width are based off these values, changing these values effectively scales the table).
* The variant_drawing_item_sizes config option will not change the text size in the individual cells. If the cell text height is set to default, it will follow the DTH for the drawing. If it is not default, it will simply remain the size it was regardless of changes to the scale of the table.
