Method

voidsetPreferredColumnWidths(final JTable table, final float[] columnWeigths, final boolean includeHeader)
This method will iterate over the given table's columns and attempt to find the optimal width for each. 
if (table == null)
    throw new IllegalArgumentException("Parameter 'table' must not be null!");
if (columnWeigths == null)
    throw new IllegalArgumentException("Parameter 'columnWeigths' must not be null!");
final int columnCount = table.getColumnCount();
final int rowCount = table.getRowCount();
if (columnWeigths != null && columnWeigths.length != columnCount)
    throw new IllegalArgumentException(
...
voidsetPreferredRowHeights(final JTable table)
This method will iterate over the given table's rows and attempt to find the optimal height for each. 
if (table == null)
    throw new IllegalArgumentException("Parameter 'table' must not be null!");
final int rowCount = table.getRowCount();
final int columnCount = table.getColumnCount();
for (int row = 0; row < rowCount; row++) {
    int max = 0;
    for (int col = 0; col < columnCount; col++) {
        final Component renderer = table.getCellRenderer(row, col).getTableCellRendererComponent(table,
...
voidsetRelativeColumnWidths(JTable table, int... widths)
Sets the preferred widths of the columns of a table to the specified percentages of the current width. 
int tableWidth = table.getWidth();
int usedWidth = 0;
TableColumnModel model = table.getColumnModel();
for (int idx = 0; idx < Math.min(widths.length, model.getColumnCount()); idx++) {
    TableColumn col = model.getColumn(idx);
    int colWidth = tableWidth * widths[idx] / 100;
    col.setPreferredWidth(colWidth);
    usedWidth += colWidth;
...
TableColumnsetTableColWidth(JTable table, int column, int width)
Sets the width of column to fixed value. 
TableColumn col = table.getColumnModel().getColumn(column);
col.setMinWidth(width);
col.setMaxWidth(width);
return col;
voidsetTableColWidths(JTable table, int... colWidths)
set Table Col Widths 
if ((table != null) && (colWidths != null)) {
    TableColumnModel tcm = table.getColumnModel();
    if (tcm != null) {
        int n = Math.min(tcm.getColumnCount(), colWidths.length);
        for (int i = 0; i < n; i++) {
            TableColumn c = tcm.getColumn(i);
            if (c != null)
                c.setPreferredWidth(colWidths[i]);
...
voidupdateTableColumnWidth(JTable table)
Calls updateTableColumnWidth(table, 5000). 
updateTableColumnWidth(table, 5000);
