UICollectionViewLayout usually supports registering decoration views as both nibs and classes. This change is to allow the SpreadsheetLayout subclass to also provide that functionality.

I'm pretty sure this is a dumb question, but is there a way to update/set the label into a decorative view programmatically ? I didn't find any example about it in the project and I don't understand how I may access to the label in order to change "Revenue" by something else

Thanks in advance

Hello, great work on the library and the fact that it relies on native UICollectionView system is great.

I'm trying to create "grouped headers" that can span over muliple columns like in the screenshot below. How would you approach it?

I was thinking about adding a large section header but the width of headers column is tied to the width of row's columns.

thanks for the awesome library!! I can just create another nib file but I was wondering how to change label text on the fly.. Things I've tried..

//First I registered decorationview as SupplementaryView

self.collectionView.register(topRightDecorationViewNib, forSupplementaryViewOfKind: SpreadsheetLayout.ViewKindType.decorationTopRight.rawValue, withReuseIdentifier: self.defaultSupplementaryViewIdentifier)

//Lastly I tried to access it under ViewKind

func collectionView(_ collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, at indexPath: IndexPath) -> UICollectionReusableView {
        guard let viewKind = SpreadsheetLayout.ViewKindType(rawValue: kind) else { fatalError("View Kind not available for string: \(kind)") }
        
        let supplementaryView = collectionView.dequeueReusableSupplementaryView(ofKind: viewKind.rawValue, withReuseIdentifier: self.defaultSupplementaryViewIdentifier, for: indexPath) as! SpreadsheetCollectionReusableView
        
        supplementaryView.headerDelegate = self
        switch viewKind {
        case .leftRowHeadline:
             if indexPath.section >= 0 && indexPath.section < self.LastPaymentReceiptArray.count {
                supplementaryView.infoLabel.text = self.LastPaymentReceiptArray[indexPath.section].partynm
            }
        case .rightRowHeadline:
            supplementaryView.adjustmentButton.tag = indexPath.section
        case .topColumnHeader:
            supplementaryView.infoLabel.text = self.topHeaderLabels[indexPath.item]
   
        case .decorationTopRight:
//Here I try to mutate the label 
            supplementaryView.infoLabel.text = "View Adjustment"
            
        default:
            break
        }
        
        return supplementaryView
    }

Hi everybody,

I would like that when a cell is selected, the cells between the selected one and the header are colored. To make you understand the idea, I post a Google Flight image that shows the result I would like to achieve. how can I do?

Adding the SwiftSpreadsheet package by branch with SPM works.

However, if you select a version number, e.g. "Up to Next Minor Version", an error message appears in a dialog.

I believe the resolution is to publish a release on GitHub.

Hi, Interesting component 🙂 For iOS projets it's will be great to make your component Carthage compatible

Take a look at these articles:

• Ruthlessly Simple Dependency Management with Carthage
• Carthage Tutorial: Getting Started
• Making Carthage-compatible Frameworks with Swift
• Swift Cross Platform Framework (section Configure targets for Carthage) 👍

On your README.md add on top and add section for the installation with Carthage.
