truncate.js | fast , intelligent javascript text truncation | Data Manipulation library

I think this has nothing to do with Sequelize, but the database instead.

At How to truncate a foreign key constrained table?, are shown some options to deal with this restriction, that could be applies in a Sequelize transaction

I'm not sure that I understand your objective, but I think that you are trying to get the spacing to be more consistent for the repeated span tags with the "@Abide Masaraure" text.

If that is so, I suggest examining the generated HTML using Chrome's Inspect feature or a similar function from another browser.

The odd spacing seems to occur because of non-breaking space characters (  ;) being inserted just before the last span tag.

Here are some images that I pulled from your plunker example to show this.

Somehow span tags are being generated with nothing in them but the non-breaking space characters.

Could your truncation logic somehow allow empty strings or spaces to be converted into these span tags with non-breaking space characters? That may be the root cause of your display issues. I hope this helps.

looks like the problem lies within the truncate function

it uses this to reference the string to truncate,
try adding the string as another parameter instead...

here, the function is used in combination with a calculated column in a DataView

see following working snippet...
