Basic indications to start to work with Tables in Euler

[JavierVelascoPosada]

@arguiot I appreciate if you can help me with this issue.
I am a beginner learning swift, I have only basic knowledge but I would like to start to use Euler.
I have written the following code to manage cells in a table with Euler

`var table = Tables()

public var dataSource: TablesDataSource?

table.dataSource?.updateCell(content: CellValue(string: "3.456"), x: 1, y: 1)

if let cell2 = table.dataSource?.valueOfCell(x: 1, y: 1) {

print(cell2)

} else {

print("error2")

}

`
The result is that nothing is allocated. Can you please help me with this issue?
Your help can help me to progress with Euler.
I am programing command line tools in Ubuntu.
Thank you very much for your help

Hello Javier,
The idea behind the table data source, is that it's up to you to implement it. Here is an example implementation:

class SimpleTableDataSource: TablesDataSource {
    // 2D array to store cell values
    private var grid: [[CellValue]]
    
    init(rows: Int = 100, columns: Int = 26) {
        // Initialize grid with empty values
        self.grid = Array(repeating: Array(repeating: .empty, count: columns), count: rows)
    }
    
    func valueOfCell(x: Int, y: Int) -> CellValue {
        // Check if coordinates are within bounds
        guard y < grid.count && x < grid[0].count && x >= 0 && y >= 0 else {
            return .nil
        }
        
        return grid[y][x]
    }
    
    func updateCell(content: CellValue, x: Int, y: Int) {
        // Check if coordinates are within bounds
        guard y < grid.count && x < grid[0].count && x >= 0 && y >= 0 else {
            return
        }
        
        grid[y][x] = content
    }
}

// Example usage:
let dataSource = SimpleTableDataSource()
dataSource.updateCell(content: CellValue(string: "3.456"), x: 1, y: 3) // Updates cell B4
let value = dataSource.valueOfCell(x: 1, y: 3) // Gets value of cell B4
