but no direct property is available,
I have tried to make width of column zero but, still it shows the column
please help if you have some idea about this.

It's an old thread, but may help someone else.
This can be easily achieved:

tableLayout1.ColumnStyles[4].SizeType = SizeType.Absolute;
tableLayout1.ColumnStyles[4].Width = 0;

You forgot to mention a side-effect of your solution. If there are other rows/columns with percentage heights/widths, you're changing the layout of the entire TLP and all controls will move/grow/shrink (depending on docking) to take up the space. This may not have a desired effect.

You're right, I've tested without anchor nor docking, and all the columns with percentage widths. The other colums recalculate automatically to fill the space, and the controls inside get centered correctly.
this is OK for me.

All I said is that may not be a desired effect for other users.
There are no actual rows and columns in a tablelayoutpanel. TLP is an extension to existing controls to control where the control paints itself. You cannot hide a row or column in the TLP.
