I'm using INdesign CS6 and have linked several tables with styles to excel spreadsheets.
We update the tables daily for daily news reports. Each time we relink the tables, we lose the table header and have to reapply the style (the other styles remain). Should add I have applied cell styles, paragraph styles and table styles.
Had read this was a bug in previous Indesign but also thought I'd read somewhere this had been fixed.
