java - How to set column width of Jtable equal to a checkbox -


below picture. enter image description here

i using following code it's not setting width size of checkbox

tablecolumn column = null;         column = table.getcolumnmodel().getcolumn(0);         column.setpreferredwidth(1);

i want remove spaces around checkbox

the tablecolumn has 3 widths, minimum, preferred , maximum.

setting width 1 makes no sense since checkbox won't paint in 1 pixel, guess minimum value being used. also, depending on auto resize property value overridden make sure column widths fill table view.

try setting minimum , preferred sizes same (reasonable) value.

a better approach not guess @ width since change different laf's. instead can use renderer determine appropriate width column. see table column adjuster basic example code can use , more complex class provides complete solution.
