TableTools export to PDF issues

Hi,

1. Is it possible to left-align the column headings in the PDF instead of centre-aligning them? I would like the column heading alignment to match the column data alignment.

2. When a PDF file already exists and you say yes when asked if you want to overwrite the PDF, the PDF is not overwritten. No errors are produced. The PDF file is not open elsewhere.

I am using the latest stable release (2.2.3) at the time of writing this post and have observed the above issues using IE11.

Thanks in advance.

Regards,
Andrew
