Is it possible to set column width in SQLite table?

I am trying to display a SQLite table in a view. I want my first column to have a width of 20 characters. I have attempted to achieve this effect by using the substring method but I get stringindexoutofboundsexceptions with strings less than 20 characters. Any help is greatly appreciated. Here is my code:

Method for displaying table in view:

public String getData() {
// TODO Auto-generated method stub
String[] columns = new String[]{ KEY_ROWID, KEY_NAME, KEY_QUANTITY, KEY_VALUE };
Cursor c = ourDatabase.query(DATABASE_TABLE, columns, null, null, null, null, null);
String result = "";

int iRow = c.getColumnIndex(KEY_ROWID);
int iName = c.getColumnIndex(KEY_NAME);
int iQuantity = c.getColumnIndex(KEY_QUANTITY);
int iValue = c.getColumnIndex(KEY_VALUE);

for (c.moveToFirst(); !c.isAfterLast(); c.moveToNext()){
result = result + /*c.getString(iRow) + " " +*/ c.getString(iName).substring(0, 20) + " " + c.getString(iQuantity) + " " + c.getString(iValue) + "\n";

Just use c.getString(iName).substring(0, Math.min(20, c.getString(iName).length()) (possibly using a temporary for c.getString(iName)) instead of the substring you have now.
