I'm not positive I understand your problem, but the following may help: 1. Labels (for cross-referencing) usually go in the table caption, although this is probably unrelated to your issue.
2. You can specify column widths by right-clicking a cell, choosing "Settings...", entering a value in the column width box, and selecting units in the drop-down list alongside it. 3. If a table is too wide (or long) and you want to scale it (rather than setting a column width, which causes text to wrap), you can put the table inside a scalebox or a resizebox. In LyX 1.6.x and earlier, that requires inserting raw LaTeX code (ERT) on either side of the table. I suspect that is also true in 2.0 but I'm not positive. Paul
