I have a complex multi-cell, multi-column, multi-row table which includes a number of paragraph styles and a handfull of character styles within it. I try to avoid having any text which is not allocated an appropriate style (says he, feeling InDesign self-righteous!) Recently I found a need to change the dimensions of the whole table (resized page margins) by choosing Table/Select/Table and then Shift-Click-dragging the bottom right-hand corner out a little to the new margin.
Sadly, I then discovered that all the text within the table had increased slightly in size (eg., what should have been 10pt became 10.201pt) and any text with the cursor inside it showed the +plus-sign beside the appropriate style in the style pallet. It has taken me ages to go through the entire table and correct them by clicking on the “Clear overrides” button at the bottom of the style pallet. The job is done but I am wondering of there is a way I could avoid this happening in the future?
