How can we protect some parts of a sheet using rubyXL? - ruby

Question

I'd like the user of my xlsx spreadsheet to edit some parts of a sheet but not the most of it. Or in other words, I'd like only some parts of the sheet to be protected.
I learned how to protect the sheet using rubyXL with the code below:
sheetProtection = RubyXL::WorksheetProtection.new(
password: hashedPass,
sheet: true,
objects: true,
scenarios: true,
format_cells: true,
format_columns: true,
insert_columns: true,
delete_columns: true,
insert_rows: true,
delete_rows: true
);
wsData = workbook['data'];
wsData.sheet_protection = sheetProtection;
Say, I'd like the user to only edit the cell range C2:C13 of the said sheet.
I can't find the syntax on how to do that from the documentation of the rubyXL nor how to use that documentation (please forgive my ignorance). I'm at a loss when I click any link on the side of that page, because for me, it seems the only friendly one is the main page. Google is not helping. In the above code, I don't know how they get the sheet_protection property of the worksheet as available for use.
In the closest clue I found, I learned that "unprotection" of a cell can be achieved by a cell style. So I tried creating a style and putting that one in a cell, but that one too proved to be difficult due to lack of guides.
In the cell_style.rb of the github repo, I found something about Protection and CellStyle classes.
unprotected = RubyXL::Protection.new(
locked: false,
hidden: false
);
unprotecStyle = RubyXL::CellStyle.new(
name: 'unprotected style'
);
I can't find in the docs how to put them together, or even apply a style on a cell:
wsData[1][2].cell_style = unprotecStyle;
# undefined method `cell_style=' for #<RubyXL::Cell(1,2): "cell-content", datatype="str", style_index=8>
I'm not even sure if I'm on the right track. Please help.

Perhaps you figured this out already, but this worked for me...
Given a worksheet and a cell, I did:
worksheet.
workbook.
cell_xfs[cell.style_index || 0].
protection = RubyXL::Protection.new(
locked: false,
hidden: false
)
Then I did:
worksheet.sheet_protection = RubyXL::WorksheetProtection.new(
sheet: true,
objects: true,
scenarios: true,
format_cells: true,
format_columns: true,
insert_columns: true,
delete_columns: true,
insert_rows: true,
delete_rows: true
)
Which protected the entire worksheet except for the cell.
