Are they all the same reference type? If so, you could create the table in a separate document and edit the output style to use the same ref type template from bibliography into the citation template, and alter the author settings to more closely match those in the bibliography. – then when you inserting the table into the document, you would first “convert citations and bibliography” to “plain text” and copy the table into your final document.
If there are two ref types, you might try to use the Author (year) template to house the other bibliography template, but it would only work if there is one citation per cell.
