Setup

const params = {
  deductionTypes: ['type1', 'type2'],
  reasons: ['reason1', 'reason2'],
};

const createMockData = (numRows = 1000, warningsPerRow = 5) => {
  return Array.from({ length: numRows }, (_, i) => ({
    id: i,
    otherData: `row${i}`,
    warnings: Array.from({ length: warningsPerRow }, (_, j) => ({
      deduction_type: j % 2 === 0 ? 'type1' : 'typeX',
      reason: j % 3 === 0 ? 'reason1' : 'reasonX',
      warningDetail: `warn${j}`,
    })),
  }));

const data = createMockData();
