C question: Why would one put 'static' variables in a header?

Not Keil specific; one for the 'C' experts:

Why would one put 'static' variables definitions in a header?

eg, in a header file:

/*
 *  TCO count to temperature  conversion table.
 */
static erTcoTableStruct tcoTableOPUS1[] = {
    /*{TCO,Temp,} */
    {1,-99},  {4,-45},  {5,-40},  {8,-35},  {11,-30}, {16,-25}, {22,-20}, {29,-15},
    {37,-10}, {48,-5},  {61,0},   {78,5},   {99,10},  {124,15}, {153,20}, {188,25},
    {227,30}, {270,35}, {315,40}, {365,45}, {420,50}, {481,55}, {549,60}, {625,65},
    {710,70}, {805,75}, {910,80}, {1010,85}, {1060,88}
};

AIUI, the whole point of so-called "header" files in 'C' is to share stuff between source files;

But the whole point of the 'static' keyword (at file scope) in 'C' is to make stuff private so that it is not visible to other modules - ie, not shared.

So I can't see why one would want to have 'static' definitions in a header?!
