It means that the linker could not link your program.

More information about why it's not able to link is needed to give you a good answer.
Almost always, the exact error is in the lines above the line you posted.

the program doesn't hv any error .. only its show that error.

before this i experience the same problem and solved it jus by reset the Qt programmg(or restart my pc)
but this i tried the same solution but it doesn't work this time...

so i don't any solution to run my program ....T_T

*Sigh*

The error means exactly like I said in my first reply. It is a linker error. Why you get this, I don't know, YOU need to provide information.

What do you use to build your program? Qt Creator?
Is your program still running when you try to rebuild it?
Did you check the compile output to know where the linking fails?

If you don't do any effort in explaining the questions above, you will not get a good answer.

Are you using QtCreator? Try switching from "Build issues" panel to " Compile Output" panel and search for errors.
I often have the program already running and the linker says: cannot open output ... permission denied ...

i'm using Qt Creator...

in compile output:

Looks like source file that contains TableEditor class was not added to .pro file and as a result didn't get into Makefile.
