# LyX Question on Table Numbering

How can you change table numbers in LyX. I want to get tables numbered within section (Table 1.1, 1.2 etc.). For some reason `\numberwithin{table}{section}` is not working.

`\numberwithin{<slave>}{<master>}` is a macro defined by `amsmath`. So, in order to use it, you need to add the following to your LaTeX Preamble:
``````\usepackage{amsmath}% http://ctan.org/pkg/amsmath
Similar functionality is provided by `chngcntr`, via macros like `\counterwithin` and `\counterwithout`. The latter package provides the means to removing any counter bindings, which `amsmath` does not offer.
