Production of tables and formatting them in Word is something I have dealt with a couple of times recently and it really is important to do something smart because of the time taken to individually format tables.

An approach I used recently was to produce a text table in R and export it to Excel as a .csv file which could then be copied as is to Word. Borders and the like would still have to be formatted individually but not entries in the table (with a minor caveat below). The tables comprised results of test with p-values and confidence intervals etc for various variables.

To produce the entries in the table I wrote a small function which pasted bits of output together and formatted numbers exactly using formatC. Often the function produced a number of cells at one time.

One difficulty I had was Excel deciding as usual that it knew better than I did what I wanted. So when I had a cell with a p-value in brackets, that was of course a negative number for example. My solution was to prepend a ' character which make Excel treat the following characters literally. Once the table has been put in Word a simple search and replace can remove the ' characters.

Overall, I was reasonably happy with the approach I took. If I have a future need I will have some ready-made functions to work from which will make life easier. I will be interested to try some of the other suggestions in this thread.
