React Spreadsheet Grid Implementation

Build a functional spreadsheet grid component in React using TypeScript. This component should allow users to display and interact with a two-dimensional grid of cells, similar to a basic spreadsheet application. This is a fundamental component for many data visualization and productivity tools.

Problem Description

Your task is to create a React component that renders a spreadsheet-like grid. The grid should be capable of displaying data in a tabular format, where each cell can contain text. Users should be able to navigate through the grid and potentially interact with individual cells.

Key Requirements:

• Grid Rendering: The component must render a grid of cells based on provided row and column data.
• Cell Content: Each cell should display its content (initially, plain text).
• Scrollability: The grid should be scrollable horizontally and vertically if the content exceeds the viewport.
• Performance: The component should be reasonably performant, especially for larger grids.
• TypeScript: The entire solution must be written in TypeScript.

Expected Behavior:

• The component will accept props defining the number of rows, columns, and the data for each cell.
• When rendered, it will display a grid where the first row and first column could potentially serve as headers (though this is not a strict requirement for the initial implementation, consider it for future enhancements).
• Users can scroll through the grid using standard browser scrollbars.

Edge Cases to Consider:

• Empty Grid: What happens if no data is provided?
• Very Large Grids: How does performance hold up with hundreds or thousands of rows/columns?

Examples

Example 1:

Input Props:
{
  rows: 3,
  columns: 4,
  data: [
    ['A1', 'B1', 'C1', 'D1'],
    ['A2', 'B2', 'C2', 'D2'],
    ['A3', 'B3', 'C3', 'D3']
  ]
}

Output:

A visual representation of a 3x4 grid in the browser, with the specified text content in each cell. For instance, the top-left cell displays 'A1', the cell to its right displays 'B1', and so on. If the grid is larger than the visible area, scrollbars should appear.

Explanation: The component takes the dimensions and content, then renders the grid accordingly.

Example 2:

Input Props:
{
  rows: 1,
  columns: 1,
  data: [['Single Cell']]
}

Output:

A single cell displaying "Single Cell".

Explanation: Handles the simplest case of a 1x1 grid.

Example 3:

Input Props:
{
  rows: 0,
  columns: 0,
  data: []
}

Output:

An empty grid or no visible grid.

Explanation: Handles the edge case of an empty grid gracefully.

Constraints

• The grid should accommodate at least 1000 rows and 1000 columns without significant performance degradation.
• Input data will be a 2D array of strings (string[][]). The dimensions of data should align with rows and columns props, although robust handling of mismatches is a good practice.
• Styling should be manageable; assume basic CSS can be applied.
• Focus on the core rendering and scrollability. Features like cell editing, formulas, or complex formatting are out of scope for this challenge.

Notes

Consider using techniques like virtualization (windowing) for rendering large grids to optimize performance. This involves only rendering the cells that are currently visible in the viewport. You might want to define interfaces for your props and cell data for better type safety. Think about how to structure your component to be reusable and maintainable.
