I wasn't suggesting that you would have colleagues that know Word VBA, but you may have colleagues that have more experience of using Word to create documents. It is their knowledge that you need to gain.
Your first task should be to examine the templates you need to work with in the Word UI.
If your cursor is in a table you will see two extra tabs in the ribbon, Table Design and Table Layout. In this case you may need to copy the table. You should also see
Range.Information property (Word) | Microsoft Learn
To check whether the borders are part of the style you will need to display the styles pane (Alt+Ctrl+Shift+S) where you will see the style in use at the cursor position highlighted. Right click on the style name and choose Modify. In the dialog click Format then Borders. If the style has borders you will see them.
If the borders have been added manually you can check the Borders and Shading dialog.
In either of the last two cases you will probably need to copy the entire paragraph. It's difficult to say for certain as your screenshot doesn't show anything useful.
