I have a document with a very large table. And the very large cell of this table looks strange, when cursor is in that cell (see screenshot).
Why it looks so?
It's by design.
When cell width exceed 30 000 pixels, cell inplace editor's height is set to 30 000, scrolling in the editor is enabled, the remaining area is hatched.
It occurs only on cell editing. Viewing and printing are unaffected.
It comes from Windows limitation on the window sizes.
I have an idea how to overcome this problem in a better way, it's to-do list.
Sorry, this problem is still not solved even in the newest version.
A height of edited cell cannot be greater than 30 000 pixels. Otherwise, its content is scrolled, the remaining has a diagonal line pattern.
