如何在Array中从数组生成列

function generateColumnsFromArray(arr, method) {
  var columns = [];

  for (var i = 0; i < arr.length; i++) {
    var element = arr[i];

    if (method === 'index') {
      columns.push([i]);
    } else if (method === 'value') {
      columns.push([element]);
    } else if (method === 'condition') {
      if (element > 5) {
        columns.push([element]);
      }
    }
  }

  return columns;
}

var array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
var columnsByIndex = generateColumnsFromArray(array, 'index');
var columnsByValue = generateColumnsFromArray(array, 'value');
var columnsByCondition = generateColumnsFromArray(array, 'condition');

console.log('Columns by Index:', columnsByIndex);
console.log('Columns by Value:', columnsByValue);
console.log('Columns by Condition:', columnsByCondition);
