Failed to set column width after jtable becomes visible

Question

I read the Oracle API hundreds of times, read countless articles, both here and elsewhere, and I still can't resize the columns after the jtable becomes visible. As you can deduce, I am also trying to set the visibility of columns using jcheckboxes. Using addColumn and removeColumn, as other articles have noted, does not return the columns to their original position. Earlier, I used an additional class to store column information, for example, the column itself, its identifier and the source index. It also became dirty, and the problem of adding / removing data after changing the visibility of the column. I noticed that the data was not in the correct column. As a result, ive chose to set the column to minWidth, preferredWidth and maxWidth.

Now, to my problem, the code below does not adjust the column width if setColumnVisible is set to true. According to Julius, Minera, why is this so?
