[Feature request]: Exporting selected data

[s1291]

Hello,

First, I want to say thank you for this software. It is very useful.

I often load files with many columns, for example:

I can filter the columns using the search box. If I search for CLift, it shows only the columns that start with CLift:

I can select those columns and plot them. However, I cannot find an option to export only the selected columns to CSV. The option under File > Export Table exports the entire dataset, all columns.

It would be great if pyDatView could export the selected columns to a .csv file and optionally include the Time column by default.

Best regards,
