Description

The list of methods to do JTable Column Width Get are organized into topic(s).

Method

int[] getColumnWidth(JTable table)
get Column Width

int[] columnWidth = new int[table.getColumnModel().getColumnCount()];
for (int i = 0; i < columnWidth.length; i++) {
 columnWidth[i] = table.getColumnModel().getColumn(i).getPreferredWidth();
return columnWidth;

String getColumnWidths(final JTable table)
Returns the column widths of a table in a formatted String .

Objects.requireNonNull(table);
TableColumnModel model = table.getColumnModel();
int count = model.getColumnCount();
StringBuilder buffer = new StringBuilder();
for (int i = 0; i < count; i++) {
 if (i > 0) {
 buffer.append(' ');
 int index = table.convertColumnIndexToView(i);
 buffer.append(model.getColumn(index).getWidth());
return buffer.toString();

int[] getColumnWidths(JTable p_Table)
get Column Widths

TableColumnModel model = p_Table.getTableHeader().getColumnModel();
int[] columnWidths = new int[model.getColumnCount()];
for (int i = 0, c = columnWidths.length; i < c; i++) {
 columnWidths[i] = model.getColumn(i).getWidth();
return columnWidths;

List getColumnWidths(JTable tbl)
get Column Widths

final List<Integer> result = new ArrayList<Integer>();
final Enumeration<TableColumn> enumeration = tbl.getColumnModel().getColumns();
while (enumeration.hasMoreElements()) {
 final TableColumn column = enumeration.nextElement();
 result.add(column.getWidth());
return result;

int getPreferredColumnWidth(JTable table, int vColIndex, int margin)
get Preferred Column Width

int width = 0;
if (vColIndex >= table.getColumnCount()) {
 return 0;
DefaultTableColumnModel colModel = (DefaultTableColumnModel) table.getColumnModel();
TableColumn col = colModel.getColumn(vColIndex);
TableCellRenderer renderer = col.getHeaderRenderer();
if (renderer == null) {
...

int getPreferredColumnWidth(JTable table, TableColumn col)
get Preferred Column Width

return Math.max(getPreferredColumnHeaderWidth(table, col), getWidestCellInColumn(table, col));

int getPreferredHeaderWidth(JTable tbl, int iColumn)
calculates the preferred header width by asking the header renderer.

TableColumn column = tbl.getColumnModel().getColumn(iColumn);
TableCellRenderer renderer = column.getHeaderRenderer();
if (renderer == null) {
 renderer = tbl.getTableHeader().getDefaultRenderer();
final Component compHeader = renderer.getTableCellRendererComponent(tbl, column.getHeaderValue(), false,
 false, 0, iColumn);
int result = compHeader.getPreferredSize().width;
