47.14 HTML Lists
The next example print a list contains numbers from 1 to 10
Then print a list from Ring List.
Finally we have a list of buttons and when we press on a button we get a message contains the clicked button number.
To start the list we uses the ulstart() function.
To end the list we uses the ulend() function.
We uses listart() and liend() to determine the list item.
#!c:ringbinring.exe -cgi
Load "weblib.ring"
Import System.Web
Func Main
New Page
{
ulstart([])
for x = 1 to 10
listart([])
text(x)
liend()
next
ulend()
list2ul(["one","two","three","four","five"])
ulstart([])
for x = 1 to 10
listart([])

47.15 HTML Tables
In this example we will learn how to generate HTML tables using the tablestart(), tableend(), rowstart(), rowend()
,headerstart(), headerend(), cellstart() and cellend() functions.
#!c:ringbinring.exe -cgi
Load "weblib.ring"
Import System.Web
Func Main
New Page
{
divstart([ :style = styledivcenter("400px","500px") ] )
style(styletable() + styletablerows("t01"))
tablestart([ :id = :t01 , :style = stylewidth("100%") ])
rowstart([])
headerstart([]) text("Number") headerend()
headerstart([]) text("square") headerend()
rowend()
for x = 1 to 10
rowstart([])
cellstart([]) text(x) cellend()
cellstart([]) text(x*x) cellend()
rowend()
next
tableend()
divend()
}

47.16 Gradient
In this example we will learn how to use the StyleGradient() function.
The function takes the style number as input (range from 1 to 60).
#!c:ringbinring.exe -cgi
Load "weblib.ring"
Import System.Web
Func Main
New Page
{
boxstart()
text("StyleGradient() Function")
boxend()
for x = 1 to 60
divstart([ :id = x , :align = "center" ,
:style = stylefloatleft() +
stylesize(string(100/60*6)+"%","50px") +
stylegradient(x) ])
h3(x)
divend()
next
}

47.17 Generating Pages using Objects
Instead of using functions/methods to generate HTML pages, we can use an object for each element in the page.
This choice means more beautiful code but slower.
The fastest method is to print HTML code directly, then using functions then using templates then using objects
(slower).
#!c:ringbinring.exe -cgi
Load "weblib.ring"
Import System.Web
Func Main
WebPage()
{
Title = "Using objects to create the Web Page content"
h1 { text("welcome") }

{
Title = "Google"
Link = "http://www.google.com"
