Please can you explain what is meant by continuous and discontinuous edge for a 2 way slab?. I do understand that  when there is > than 1 span , common edge of both the adjoining edge is called a continuous edgee but those slab edges where there is no further slab is called a discontinuous edge. This doesnt seem to make sense though  .

Also what is long and short edge in a slab

Also In designing the 2 way slab attached below  

working out the moment coefficients from Table 6.10.3.2 (see attached), Don't quite understand why
For Panel A -  2 short edges are discontinous
For Panel B-   1 long edge is discontinous
For Panel C-   4 edges are continuous
For Panel D-   1 long edge discontinous

But when working out deflection coefficient using  table (Table9.3.3) for differrent edge conditions(continous and discontinous)
For Panel B- 4 edges continuous instead of 1 long edge discontinous as above.
I would appreciate if you kindly provide explanatory information about this. Thanks for being on this forum.
