web2py add row in form table - row

Question

I'm building an edifact translator/editor. For displaying an existing translation I have the following controller:
import shutil
import sys
import fileinput
def edit_datafile():
#inlees gedeelte van een bestaand datatype
file = open('/home/wouter/DESADVCB.pcf', 'r')
datas = []
data = {}
row = {}
j = 1
for line in file:
meg = line.strip().split(':', 3)
if line.startswith('#'):
c = 1
unmark = line.strip().split('#')
datas.append('#')
datas.append(unmark[1])
data[j,c] = datas
datas=[]
j = j+1
else:
if '.' in meg[0]:
t = meg[0].split('.')
if '+' in t[0]:
a = t[0].split('+')
datas.append(a[0])
datas.append(a[1])
else:
datas.append(t[0])
datas.append(t[1])
try:
t[2]
datas.append(t[2])
except IndexError, e:
datas.append('')
else:

datas.append(meg[2])
try:
meg[3]
if ':' in line:
reg = meg[3].strip().split(':')
c = 1
for teg in reg:
seg = teg.split('=')
if '.' in seg[0]:
t = seg[0].split('.')
datas.append(t[0])
datas.append(t[1])

datas.append(t[2])

I want to be able to add rows in the form without a submit on a desired position. I have looked at powertable, datatables and jQuery to accomplish this but I cannot seem to find a suitable solution.
Can someone help me?

Answer 1

If I understand correctly, you need to add row dynamicly to the table in any position.
If so, you can use jQuery method before() or after().
For example, to insert row before selected row:
$('#table tbody tr').live('click',function(event) {
$(this).before("<tr><td>data1</td></tr>")
});
