You can override the spacing by the @
operator (find more on e.g. https://en.wikibooks.org/wiki/LaTeX/Tables). So by {l@{}c@{}l}
you completely remove the inter column spaces. Probably you want some spaces, and then you can add it as for example {l@{\ }c@{\ }l}
. In the nelow example I have also added one version where only one column is used. I do not really see the reason for three (as it is given in this example).

. If that is not what you are looking for try to clarify the question. It often helps to give a minimal working example (MWE) that shows the problem.tabular
, which seems unnecessary. Secondly, if you don't want any spaces between the columns, then you don't need columns, really...
