File widget: read file without header

[alaindebecker]

What's your use case?

I have files with no header: the first row of my files are data, so the workaround suggested in https://github.com/biolab/orange3/issues/6675 (right click on the row index to skip it) does not work: the first row is lost forever.

What's your proposed solution? Add a number field Number of row for Header.

• If it is 0, take arbirary names for columns (1,2,3,...), and rename them later.
• If it greater than 1, it will solve issue-6675, comment-1854075827.
• Compatibility with previous uses is ensured if the default value is 1.

Are there any alternative solutions? Do it manually with an editor.

+1 very common use case and the proposed solution is the simplest one.

@alaindebecker, a related trick to #6675 should already work. In CSV File Import, right-click the row number and deselect header (instead of choosing to skip). Then, columns are just indexed.

Note to self: I was assigned to this to add a hint above the box, telling the user that headers are right-clickable.
