We are using latest version of flying saucer v 9.1.20, In that the table columns are collapsed when there are large number of columns (Eg: 80 columns).
We have also added word-wrap: break-word for cells to break the word when needed and also used table-layout: fixed for tables.
It works when the column count is low, but when columns gets increased, the property is not being applied and column gets collapsed.
Have attached the screen shots and sample code. Have anyone faced this issue, kindly let us know the solution for this.
