<s>Human: 从一段英文文本中提取出所有的日期，并将其列在一个表格中，包括每个日期出现的次数。
"The conference will be held from July 1st to July 5th in 2022. The deadline for submission is June 15, 2022."
</s><s>Assistant: |日期|出现次数|
|---|---|
|July 1st, 2022|1|
|July 5th, 2022|1|
|June 15, 2022|1|

使用Python语言可以完成这个任务。具体代码如下所示：

```python
import re
from collections import Counter

text = "The conference will be held from July 1st to July 5th in 2022. The deadline for submission is June 15, 2022."

# 日期格式的正则表达式，包括月份、日期、年份等信息
date_regex = r'(Jan(?:uary)?|Feb(?:ruary)?|Mar(?:ch)?|Apr(?:il)?|May|June?|July?|Aug(?:ust)?|Sept?(?:ember)?|Oct(?:ober)?|Nov(?:ember)?|Dec(?:ember)?)\s+(\d{1,2}(?:st|nd|rd|th)?)(?:[\s,]+)(\d{4}|\d{2})'

# 使用正则表达式从文本中提取日期
dates = re.findall(date_regex, text)

# 将二维数组转为一维数组
dates = [date for date in dates if all(date)]

# 统计每个日期出现的次数
date_counts = Counter(dates)

# 打印日期及出现次数的表格
print("|日期|出现次数|")
print("|---|---|")
for date, count in date_counts.items():
    print(f"|{date[0]} {date[1]}, {date[2]}|{count}|")
```

注意，这个正则表达式只适用于英文日期的提取。如果遇到非英文的日期格式，需要使用不同的正则表达式。
