How to allign the Content of Cell according to some Condtion
I wants to allign the cell Left if the content is String and
to allign the cell Right if the content is a numerical(int ,long, double )
In this few cell are Rendered ,and the remaings are not.
So how i can go ahead?
I checked few of the column with renderer, are working fine with setHorizontalTextPosition(SwingConstants.RIGHT) code.
But myTable is contain 25 columns.
I plans to check the dataType of column,then use the switch case,but which method will be helpful for that?
please suggest.Thanks in Advance

The right approach will be to set the alignment in the renderer. If each cell is a bean, you can set the "data type" or else determine the alignment based on the row/column.

Associate a cellrender with a column class with the setDefaultRenderer method and create your own renderer like :
private class MyTableCellRenderer extends DefaultTableCellRenderer {
public MyTableCellRenderer() {}
public Component getTableCellRendererComponent(JTable table, Object value,boolean isSelected, boolean hasFocus,int row, int column) {
Component cell = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
// Do what you want with the cell
cell.setBackground(new Color(255,200,200));
return cell;
}
}

JTable already has different renderers to do this. You just need to tell the table the type of data in each column and it will use the appriate renderer:
