I have designed a long table, the problem is that this table is displayed in the bottom of the document and even when a paragraph is set to be displayed after the table it's displayed before the table. I have also used [!ht] to maintain the table where I want but it didn't seem to influence on it.

[!h]is nottnotpnotbso it stops the table being placed in almost all the float areas so going to the end of the document is the most likely outcome. – David Carlisle Oct 20 '17 at 19:28tableenvironment? – Przemysław Scherwentke Oct 20 '17 at 19:31
