How to make table numbering as table section_number alpha

Question

I would like the numbering of tables in a section to be in the following format:

Table section_number alpha: table caption.

For examples, tables of section 4.3 should look like:

Table 4.3 a: Table one of section 4.3

Table 4.3 b: Table two of section 4.3

How can I do it?

Thanks!

Writing this in your preamble:

\usepackage[labelfont={bf, sf}]{caption}
\usepackage{chngcntr}
\counterwithin*{table}{section}
\renewcommand{\thetable}{\thesection~\alph{table}}

should produce table labels and counters as you describe (unsure you want the label in sans serif font!). Here is an example produced with that code in a standard class of documents:
