Java Utililty Methods JTable Column Pack

void packColumn(JTable table, int colIndex)
Sets the preferred width of a column of a JTable specified by colIndex.

DefaultTableColumnModel columnModel = (DefaultTableColumnModel) table.getColumnModel();
TableColumn column = columnModel.getColumn(colIndex);
int width;
TableCellRenderer renderer = column.getHeaderRenderer();
if (renderer == null) {
 renderer = table.getTableHeader().getDefaultRenderer();
Component component = renderer.getTableCellRendererComponent(table, column.getHeaderValue(), false, false,
...

void packColumn(JTable table, int colIndex)
pack Column

TableColumnModel colModel = table.getColumnModel();
TableColumn col = colModel.getColumn(colIndex);
int width = 0;
TableCellRenderer renderer = col.getHeaderRenderer();
if (renderer == null) {
 renderer = table.getTableHeader().getDefaultRenderer();
Component comp = renderer.getTableCellRendererComponent(table, col.getHeaderValue(), false, false, 0, 0);
...

void packColumn(JTable table, int vColIndex, int margin)
Sets the preferred width of the visible column specified by vColIndex.

DefaultTableColumnModel colModel = (DefaultTableColumnModel) table.getColumnModel();
TableColumn col = colModel.getColumn(vColIndex);
int width = 0;
TableCellRenderer renderer = col.getHeaderRenderer();
if (renderer == null) {
 renderer = table.getTableHeader().getDefaultRenderer();
Component comp = renderer.getTableCellRendererComponent(table, col.getHeaderValue(), false, false, 0, 0);

void packColumn(JTable table, int vColIndex, int margin)
Sets the preferred width of the visible column specified by vColIndex.

TableColumnModel colModel = table.getColumnModel();
TableColumn col = colModel.getColumn(vColIndex);
int width = 0;
TableCellRenderer renderer = col.getHeaderRenderer();
if (renderer == null) {
 renderer = table.getTableHeader().getDefaultRenderer();

void packColumn(JTable table, int vColIndex, int margin)
PackColumn sets the preferred width of the visible column specified by vColIndex.

void packColumns(final JTable table, final int margin)
pack Columns

for (int index = 0; index < table.getColumnCount(); index++) {
 packColumn(table, index, margin);

void packColumns(JTable table)
Adjusts the widths of columns to be just wide enough to show all of the column headers and the widest cells in the columns

for (int columnIndex = 0; columnIndex < table.getColumnCount(); columnIndex++) {
 packColumn(table, columnIndex, 2);

void packColumns(JTable table, int margin)
pack Columns

for (int c = 0; c < table.getColumnCount(); c++) {
 packColumn(table, c, 2);

void packColumns(JTable table, int width)
pack Columns

int padding = 5;
TableColumnModel columnModel = table.getColumnModel();
int[] widths = new int[columnModel.getColumnCount()];
for (int j = 0; j < table.getRowCount(); j++) {
 for (int i = 0; i < widths.length; i++) {
 TableCellRenderer renderer = table.getCellRenderer(j, i);
 Object value = table.getValueAt(j, i);
 Component component = renderer.getTableCellRendererComponent(table, value, true, true, j, i);
