tdconnect(USP)

Name

tdconnect : merges <td></td> blocks

Synopsis

Usage   : tdconnect [-l<label>] num=<n> <html>

Version : Tue Jan  9 09:02:34 JST 2024

Edition : 2

Description

Horizontally merges <td> elements within a <tr> block surrounded by

a <label>.  The number of <td></td> elements merged is <n>. The

values within the <td></td> blocks are checked from left to right in

order, and if consecutive values are the same then the blocks are

merged.  The attribute colspan="<number merged>" is added to the

<td> element and the <td> blocks that were removed are commented out.

<th> elements are also merged in this way.

Warning

1. The <tr> and </tr> elements must be by themselves on different

   lines.

2. The <td>..</td> or <th>..</th> must be independent blocks (can

   span multiple lines).

3. The area enclosed by <label> cannot contain elements other than

   <tr> or <td>.

4. If there are merged cells in the input html file, <td> elements

   that are not to be displayed must be exist as comment like

   follows:

   <!-- <td>....</td> --> or <!-- <th>....</th> -->

Bug

If the data is not in HTML format as expected by tdconnect, then the

output of tdconnect is undefined.
