Vue Dynamic Table (Rows × Columns)

What you’ll build / What this tests

This premium vue coding focuses on Vue Dynamic Table (Rows × Columns). You’ll apply vue and components thinking with easy level constraints. The prompt emphasizes Generate a dynamic table in Vue 3 from row/column inputs. Normalize inputs (clamp to 0/1), rebuild….

Learning goals

• Translate the prompt into a clear vue API signature and return shape.
• Apply vue, components, reactivity techniques to implement vue dynamic table (rows × columns).
• Handle easy edge cases without sacrificing readability.
• Reason about time/space complexity and trade-offs in vue.

Key decisions to discuss

• Define the exact input/output contract before coding.
• Choose iteration vs higher-order methods for readability.
• Prioritize predictable edge-case handling over micro-optimizations.

Evaluation rubric

• Correctness: covers required behaviors and edge cases.
• Clarity: readable structure and predictable control flow.
• Complexity: avoids unnecessary work for large inputs.
• API discipline: no mutation of inputs; returns expected shape.
• Testability: solution is easy to unit test.

Constraints / Requirements

• Render the dynamic table UI as the main component.
• Provide two numeric inputs: one for the number of rows and one for the number of columns.
• Provide a button (e.g. "Generate table") that rebuilds the table when clicked.
• Render an HTML table whose number of rows and columns matches the current input values.
• Each cell should display something simple and visible, such as its row/column indices (e.g. R1C1).
• Initially, it is fine to show an empty state or no table. After clicking the generate button, a…
• Changing the row or column values and clicking the button updates the table dimensions.
• If the user enters non-positive values (0 or negative), the implementation may render no rows/columns or clamp the…
• Use Vue 3's Composition API inside .
• Use ref to store the numeric inputs and the rows/cols arrays that drive rendering.

Mini snippet (usage only)

// Example usage
const input = /* vue dynamic table (rows × columns) input */;
const result = solve(input);
console.log(result);

// Edge case check
const empty = input ?? null;
const fallback = solve(input);
console.log(fallback);

// Expected: describe output shape, not the implementation
// (no solution code in preview)

Common pitfalls

• Mutating inputs instead of returning a new value.
• Skipping edge cases like empty input, duplicates, or nulls.
• Overlooking time complexity for large inputs.
