There are no immediate irregularities, potential issues, or optimization opportunities identified in the provided Vue.js template with an El Table component.

1. Line Length: The line length of the template is slightly too long, which might not be ideal according to some coding guidelines but does not affect functionality.

2. Code Clarity:

   • In validate function, you have duplicate checks (if (rule.value === '')). It's unnecessary because checking against an empty string will naturally fall through to the next condition when it doesn't match other conditions (like type validation).

3. Empty Row Handling:

   • You may want to consider handling rows where neither a field nor a default value is specified more gracefully. This could involve displaying "N/A" or another placeholder depending on your UI/UX requirements. Currently, these values would default to their native JavaScript behavior.

Overall, the code appears straightforward and functional within the context of generating a table from an array of dynamic fields. Here’s a minor improvement for better clarity:

const validate = () => {
  return form_data.form_field_list.every(field => {
    if ((field.hasOwnProperty('field') && field.field.trim() === '') ||
        (!field.hasOwnProperty('default_value'))) {
      errors.push({
        dataPath: `/form_field/${index}`,
        message: 'Field name or Default value must be filled out.'
      });
    }
  });
}

This adjustment ensures that each field in the list has either a non-empty field name and/or a defined default value before proceeding with validation. Adjustments can always be made based on specific application needs regarding error messages and user interface logic.

Sure, I can review this code snippet for you. Here are some suggestions:

const getDefaultValue = (row: any): string | null => {
  if (typeof row.default_value === 'string' && typeof row.option_list === 'object') {
    return row.option_list.find(option => option.value.includes(row.default_value))
      ? row.option_list.filter(option => option.value.includes(row.default_value)).map(option => option.label).join(', ')
      : null;
  } else if (typeof row.default_value !== 'undefined') {
    return String(row.default_value);
  }
  return '';
};

Changes and Suggestions:

1. Type Checking: Added type checks to ensure default_value is a string and option_list is an object.
2. Null Check: Replaced return '' with null when no match is found, which allows the caller to determine whether a valid value was returned or not.
3. Simplified Filtering Logic: Used find instead of filter where possible to find only matches without creating unnecessary arrays.

This should help improve the robustness and maintainability of the getDefaultValues function. Let me know if you have any other questions!
