Question

Initsort argument was obtained only from first %TABLE(initsort)% on topic. Other tables with initsorts were sorted with args of first one.

Tested:

• TWiki version: 20011201
• Web server: Apache of course (1.3.19)
• Server OS: SuSe Linux 2.4.4
• Perl v5.6.0
• Web browser: IE5
• Client OS: Windows NT

Wasn't sure if this should go into TablePluginDev or here. (Here! Plugins web is already too busy!)

I had the TablePlugin installed on our TWiki site and was doing fine. I could have multiple tables on a single page all sorting according to different criteria and different directions. I just downloaded the newest (05-Jun) version of the Plugin and have lost the ability to specify the sorting on multiple tables within the same page.

In my Apache error log I have a lot of:

[Wed Jun 19 13:02:12 2002] view: Use of uninitialized value in string eq at ../lib/TWiki/Plugins/TablePlugin.pm line 302.

[Wed Jun 19 13:16:48 2002] view: Use of uninitialized value in subtraction (-) at ../lib/TWiki/Plugins/TablePlugin.pm line 297.

• Web server: Apache of course (1.3.24)
• Server OS: Solaris 2.8

Answer

Not Preceeded by TABLE

Preceeded by TABLE{ initsort="3" } :

Table 2	AAA	BBB
7	6	1
2	16	5
6	4	33
1	10	99

Not Preceeded by TABLE

Preceeded by TABLE{ initsort="2" } :

Table 1	AAA	BBB
yyy	aaa	uuu
aaa	bbb	aaa
uuu	eee	lll
www	ggg	iii

Preceeded by TABLE{ initsort="1" } :

Table 3	AAA	BBB
i	t	s
i	r	i
k	e	h
t	p	s
w	e	u

note: Only one "column-header click" sort can be active in any topic. Any initsort setting for the table is superseded by clicking a column header to sort.

The fix should be attached; incorporates changes in TablePlugin.pm function emitTable().

To fix the multiple-table sort problem, make this simple change to the file TablePlugin/Core.pm

# NOTE: Modified by Raymond Lutz to allow multiple tables to be sorted on one page.
# On second pass, $sortCol is defined from the last table, and it then undefines the
# sort flag. This is simply commented out, and parameters set according to the current
# value of $initSort.

#    if ( defined( $sortCol ) ) {         # COMMENT OUT
#        undef $initSort;                   # COMMENT OUT
#    } elsif( defined( $initSort ) ) {   # COMMENT OUT
     if( defined( $initSort ) ) {           # MODIFY elseif TO if
        $sortCol = $initSort - 1;
        $up = $initDirection;
        $direction = $up ? 0 : 1;
        $requestedTable = $tableCount;
    }

This does set the initial sorting state for multiple tables. But after that it is no longer possible to sort on a different column; the initsort value is kept.

In the TestCases web (in SVN) is a page with TablePlugin tests. It is really helpful to see what effect a code change has on all table variations.
