java - Formatting Integers in JTable Column Cells With Commas -

i have price column displays integers in plain format 1000000. know how can format commas without affecting value when retrieving table.getvalueat()?

is there method table.setcolumncellformat(decimalformat)?

you need custom tablecellrenderer can format value way need it. see using custom renderers more details
