I am developing an application in which I need much handling tables.

The problem is that I was not to be that some columns of the tables are increasing drastically in size by sliding the other columns to the left, the problem usually happens to me the first column. And try in many ways and nothing works.

When the table has many columns (+10), the column headers are moved from their correct position, to the point where the heads are in the midst of two columns

Try hiding the first column of the table, but does the same with the next column, I do not know if it is webdev error or something I'm doing wrong.

Thanks for all your help.
