How can I render [webform_submission:values] in a table?

You can use the Webform tokens from submitted data as following guide:

[webform_submission:values:?]

Omit the '?' to output all values. Output all values as HTML using [webform_submission:values:html]. To output individual elements, replace the '?' with…

element_key
element_key:format
element_key:raw
element_key:format:items
element_key:delta
element_key:sub_element_key
element_key:delta:sub_element_key
element_key:sub_element_key:format
element_key:delta:sub_element_key:format
element_key:delta:format
element_key:delta:format:html
element_key:entity:*
element_key:delta:entity:*
element_key:delta:entity:field_name:*
element_key:sub_element_key:entity:*
element_key:sub_element_key:entity:field_name:*
element_key:delta:sub_element_key:entity:*
element_key:checked:option_value
element_key:selected:option_value

• All items after the 'element_key' are optional.
• The 'delta' is the numeric index for specific value
• The 'sub_element_key' is a composite element's sub element key.
• The 'checked' or 'selected' looks to see if an 'option_value' is checked or selected for an options element (select, checkboxes, or radios)
• The 'option_value' is options value for an options element (select, checkboxes, or radios).
• The 'format' can be 'value', 'raw', or custom format specifically associated with the element
• The 'items' can be 'comma', 'semicolon', 'and', 'ol', 'ul', or custom delimiter
• The 'entity:*' applies to the referenced entity
• Add 'html' at the end of the token to return HTML markup instead of plain text.

For example, to display the Contact webform's 'Subject' element's value you would use the [webform_submission:values:subject] token.

Then you can use your custom style by adding them into table or list
