[TYPO3-project-seminars] 0.7.3 - Empty column by setting of hideColumns property

[Sergio Eures]

Hello people,

I've noticed that, in frontend, by setting of the hideColumns property, it
results an empty column (maybe 10-15px large) at the very beginning of the
column names:

|...|  Title  |  Date  |  City  |  Organisers  |

By using the default parameters, instead, the empty column is not present:

|  Title  |  Number  |  Date  |  Regular price  |  Vacancies  |

Is that a bug?!...
