I have a basic table in the tabular environment, and I want to fill a cell with a dash, to show that there is nothing to go in that cell. I've tried just using dash, but can't get one that's long enough or connected.

\hrulefill perhaps or that may be a bit low or you can use \rule to make any rule of any fixed length and height above the baseline – David Carlisle Apr 9 '13 at 10:31
perhaps the cancel package can be of use here (or perhaps tex.stackexchange.com/questions/20643?) – Sean Allred Apr 9 '13 at 10:45
\hrulefill does what I want it to, but it also messes up my cell colouring, where I've used \rowcolor – Danger Fourpence Apr 9 '13 at 10:46
I'd simply use -- or --- – egreg Apr 9 '13 at 10:50
@egreg I've tried those, they're too narrow for my liking – Danger Fourpence Apr 9 '13 at 11:01

Here I define a \longdash command, by default it's (slightly less) than an em-dash; it has an optional argument: \longdash[4] is (slightly less than) four en-dashes.

\NewDocumentCommand{\longdash}{ O{2} }
  --\prg_replicate:nn { #1 - 1 } { \negthinspace -- }

Foo & Bar column & Baz column \\
123 & 456 & 789 \\
\longdash & 42 & \longdash[2] \\
\longdash & \longdash[3] & \longdash[4] \\

Filling with \rowcolor involved seems tricky and, in my opinion, not desirable. However, I would recommend simply using an em-dash for this.
