Question

I have a table named tblMainData with several columns with a couple of them with width of 0.

I want to store the all data in the table except those columns with 0 width to a two dimensional array.

How do I check to see if a particular column has 0 width?

Answer 1

Just call TableColumn#getWidth():

for(int col = 0; col < tblMainData.getColumnCount(); col++)
{
    if(tblMainData.getColumn(col).getWidth() == 0)
    {
        // do something
    }
}
