How to force the table orders in Latex

Question

I have several tables and some of them are long tables. LaTeX displays them in different order than I want.

Say, I would like to order them as

table 1
table 2
table 3(longtable)
table 4
table 5
table 6(long table)

But LaTeX orders it like

table 1
table 2
table 3(longtable)
table 6(long table)
table 4
table 5

How can I force the order as I want?

Answer 1

Latex floating tables never float out of order. However as is mentioned in the documentation longtable doesn't float so tables can float past it, out of order. The simplest solution is to put \clearpage before the longtable to prevent floats floating past.
