如何通过循环生成数组数据替换tabella.js表头测试数据？

Got it, let's sort this out! You're looking to replace that hardcoded dataTest.tableHeader with dynamically generated arrays that follow mathematical patterns, instead of the fixed ranges you're using for testing. Here are a couple of practical approaches to do this:

Basic Linear Pattern Generator #

If you want to replicate the structure of your original test data (ranges with consistent step sizes), you can create a reusable function that builds these intervals based on your desired math rules. For example, your original data starts at 6534, jumps to 6756 (a step of 222), then uses 100-wide intervals after that. Here's how to automate that:

// Function to generate table headers with configurable math rules
function generateLinearHeaders(startValue, endValue, initialStep, intervalWidth) {
  const headers = [];
  
  // Add the first custom interval matching your 6534 -> 6756 example
  headers.push([startValue.toString(), (startValue + initialStep).toString()]);
  
  // Start the loop from the next value after the first interval
  let currentStart = startValue + initialStep + 1;
  
  while (currentStart <= endValue) {
    const currentEnd = Math.min(currentStart + intervalWidth - 1, endValue);
    headers.push([currentStart.toString(), currentEnd.toString()]);
    currentStart = currentEnd + 1;
  }
  
  return headers;
}

// Replace your hardcoded test data with the generated headers
var dataTest = {};
// This will match your original test structure exactly
dataTest.tableHeader = generateLinearHeaders(6534, 8400, 222, 100);

Custom Mathematical Patterns #

If you want more complex math (like squared values, multiples, or custom formulas), you can adjust the function to calculate interval starts/ends using any formula you need. For example, generating intervals based on squared integers:

// Generate headers using squared values as interval starts
function generateSquaredHeaders(startInt, endInt, intervalOffset) {
  const headers = [];
  
  for (let i = startInt; i <= endInt; i++) {
    const intervalStart = i * i;
    const intervalEnd = intervalStart + intervalOffset;
    headers.push([intervalStart.toString(), intervalEnd.toString()]);
  }
  
  return headers;
}

// Usage: Generate intervals starting at 80² (6400) up to 91² (8281), each +100
dataTest.tableHeader = generateSquaredHeaders(80, 91, 100);

Key Notes for tabella.js Integration #

• Once you generate the tableHeader array with either function, just assign it to dataTest.tableHeader like you did with your hardcoded data—tabella.js should pick it up seamlessly.
• Feel free to tweak the functions to match your exact mathematical requirements: adjust step sizes, formulas, or even add conditional logic for irregular intervals.
