Tables/columns in PDF export corrupted when images are inserted to table

Summary

Tables in PDF are corrupted when images are inserted to table

Environment

Confluence 6.2.3, Linux64bit, Chrome 55.0.2883.95 (64-bit)

Steps to Reproduce

1. Create table1 3 columns by 4 rows
2. Before inserting any data adjust columns width
3. Insert jpg pictures to one column, add some text to other columns (I resized each picture size by 1px as workaround to other bug related with images not displayed in PDF export CONFSERVER-34385)
4. Create table2
5. Don't change columns widths
6. Insert the same images as for previous table1 and insert some text in remaining cells.
7. Save the page
8. Export page to PDF

Steps to reproduce recording

Expected Results

Table1 and Table2 exported to PDF will have the same column widths as in Confluence page

Actual Results

Columns widths in PDF file for Table1 are sized evenly which is different than original Confluence page

Workaround

• Install plugin "Confluence Source Editor"
• Go to problematic page and click on edit. Enter source editing mode.
• Find table which is not rendered properly in PDF file
• Remove content containing <colgroup></colgroup> tag
