如何匹配包含每个元音的单词至少一次？

def match_vowels(words):
    vowels = {'a', 'e', 'i', 'o', 'u'}
    table = {}
    for word in words:
        if len(word) == 0:
            continue
        count = 0
        for c in word:
            if c in vowels:
                count += 1
        if count == 0:
            continue
        if word not in table:
            table[word] = count
        else:
            table[word] += count
    result = []
    for word in table:
        if table[word] == 0:
            continue
        result.append(word)
    return result
